Almost begged me to build one last night and I told him I will give you an answer after I check on something today. Well I called him back with an answer this morning. I have one Keith Black block, one mega blocks, one 48 degree R block, a 59 degree R3 block, 3 stock 440 blocks, one 340 block, and 13 ( 360 blocks ). I turned down a 360 complete engine with a 727 bolted to it over the weekend for 50 dollars but may go back and grab it. After I told my friend the numbers of blocks I have he kinda understood but said he would still love to see what I could do with one. I guess if on fell in my lap it would be kinda fun.

I have wondered why I have not looked into gen 3 also. Can get good flowing heads and blocks seem to be stronger then old BB. Think a new hellcat block is $1500.

They are a good eng and have their place but I would never put one in my 63. The 62 to 65 Mopars are the Max Wedge and Gen II Hemi era and thats what I prefer in mine. Nothing wrong with using the Gen III Hemi if that's what you want. Ron

We had parts for two complete 5.7's at work that we had gathered from various jobs.... sat on them for years. Absolutely no value. basically gave them away to a scrap guy. About 3 years after that people started builds using them. Guess I should have held out a little longer.

When I see what guys are paying for rockers, intakes, cams, ect, ect, ect, I catch myself shaking my head. Some guys have switched to FI only to pay big money and really struggle with it for zero performance gains. But I'm thankful of the generation 3 because its really made for some good deals on the "old junk" parts. LOl
Just gotta keep some spare change in your pocket for when a deal comes along.

Pick up the 360/727!!!
I sure would.

Pretty sure I passed the deal on to my friend. I honestly am set pretty good but it's a sure money maker if you need some quick cash. I just hate selling stuff once it's taken apart and stored in my shop

Super heads out of the box, good stock blocks, but few choices for intake systems ,cam control and ignition. Ma Mopar could have kicked off a great start for this engine family by providing low to reasonably priced parts for hot rodders and racers, but chose not to. Sad.
I have thought that an eight stack constant flow alky injected Gen 3 would make a great race motor, with 800+ hp reasonably easy to reach, and very light for the power.

I got a blown up 5.7 for free and rebuilt it, collected a bunch of parts for it and there it sits. I wanted carbureted and have a couple intakes and so on. Nothing happened.

Plan B was, I've got two vehicles with 5.7s of the same vintage, one of them is my truck with 250,000 miles on it. It's really not worn out enough to change it. If I ever sold that other engine sitting there, the truck would probably throw a rod through the block the same day.

This is how I see it also............the only late model for me is my daily driver and even though they've proven to make power, just like turbos today, no thankxx................

I'm nibbling around the edges of the G3 deal now. Just bought a pair of Eagle heads that I can't wait to get on the flow bench. Mopar says 300+ CFM. We'll see. But I'm just as interested in the low and mid lift numbers.

I might like to try a stroked 5.7 (392) around 11:1 CR, 250-ish cam, single 4bbl intake, 950 carb. If I see it to completion, I'd sure be tickled if it'd go high 10's in a 3000# A body and be 100% pump gas street friendly.

On principal I agree with some; a G3 doesn't seem "right" to me in some applications; ie Ron's example of an early B-body. But in an A body, they seem right at home to me.

Sounds like you have a stash of good parts sitting there so for you it wouldn't make any sense.

The argument that they're prohibitively expensive gets holes poked in it pretty fast though. Rocker Arms are expensive, but a good set of quality rockers for a SB or BB aren't far behind. You can get a good intake now for $500. Cam, last I looked a roller cam set for a SB or BB was $800, in line for what you pay for a Gen III (although all you need is a cam ($400 ish), factory lifters are good for 7K and you can convert them to solids). Rotating assemblies are a wash. Where you get some $$$ back is you can walk into a junkyard and leave with a cross bolted 800+ hp capable block (reliably) and heads that flow 300+ before porting (Eagles), to get those capabilities with a SB or BB you need to look at the aftermarket. Yes you can't buy $89 Summit Racing flat tappet cams but that's not the type of build you're looking at.

Stick with what you're comfortable with and giver

Im just curious because Im still learning. At what point do you need to buy rockers, because I just got off the phone with Arrow Racing and they use stock rockers in their Trans Am motors and the cascar(candian nascar) series


And Goss made many 200mph passes with a stock block before he ran over the crank

My 2 cams i bought, custom grinds were under $350 so ptbgracer you must be shaking your head at the money you waste on them 13 360s. Lolol

Good point, the factory Gen III rockers are very capable as is, to get a SB/BB to an equivalent capability would require decent aftermarket rockers.

The big stumbling block to me is no dist. So no basic low budget build, big money right from the start. After accumulating parts all these years none work on the engine, you start from scratch. Lap tops, FI, fuel rails and injectors, o2 sencers, for us older guys a little intimidating. Never have had to pull heads just to change lifters-cam. Bad part, I got three looking at me right now while scratching my a$$.

MSD 6 hemi kits are around $700 ish, not far off what a good distributor/coil/ignition controller would put you back

A few years ago I picked up a complete 48,000 mile takeout 2008 SRT 6.1 with NAG trans at a pretty good price. No real plan yet, but it is sitting next to a '69 Coronet R/T hardtop shell.

I may end up selling some cars to finance future projects. The wife ran up my credit cards, so might take awhile to pay them off

You undo the rockers, pull the pushrods and rotate the engine. The lifters get pushed over to the side and you swap cams.

Next, support a moparts member and get yourself a nice Thumpercarb(even though he wants to live in the past and hates on the new stuff every chance he gets) and put it on a $500 intake. Get a hemimsd6 and hook up all 5 wires and start it up.

Anybody want to buy 3 old out-dated 440 blocks. LOL

List them in resto section. They are useless

I know this is not an everyday ocurance but I just picked up a 2011 eagle 5.7 hemi off CL with 109,000 miles for $300, (I have picked up a couple of earlier ones around that price), opened it up to see if he sold me some junk, everything looked like new so I am stuffing it in my truck right now to get it running while I build the good motor. The good motor is going to have a SRT 392 cam ($68) from the dealer(.577 lift) I am gonna bump compression and quench up for $200 at the machine shop, the heads that flow as much as a real good ported W2 heads. Arrow racing has a nice looking intake for $500ish carb or EFI but if your going EFI the factory intakes are pretty awesome. There is some sticker shock on headers and oil pans but if your getting real good SB stuff than they are comparable. There is pros and cons to both but if your buying stuff from scratch you got to look real hard at the gen III. If your buddy has to buy an X block from you and pay you for some W2s that flow 330+ CFM then he has just leveled the playing field on price plus he don't have aluminum heads, lightweight plastic intakes, cheap 7000+ RPM hydro roller lifters, and far better oil control yet. My truck has 300,000 miles, used zero oil and the cylinder walls look almost new.

I'll guarantee you this. I can take one of those "useless blocks" and beat 99% of the Gen 3 Hemi's. LOL. And cheaper too because I buy used.

Tell me how you would do it? And dont say I would bolt on b1 heads that I have sitting on the shelf.

I can't let out all my secrets but I don't see many NA gen 3's running 8's and low 9's in the 1/4. Plus most of the guys must be afraid of racing light cars and prefer tanks.

One thing I have become very aware of lately. A couple friends want my help porting there own heads. I have come to realize that grinding metal away is not very easy for people and you take that for granted. You have skills and tools that other don't so you cant make the claims you make because others simply can not duplicate it. It could cost someone else easily thousands of dollars to do what your doing in your free time.

But you cant go to the junk yard and get a set of heads that flow over 300cfm for any sb or bb mopar

Why did you post this question? We get it, you hate Gen III Hemis, you don't want to build one, why post about it? Take a look at the times guys are running with their "tanks" and extrapolate their power into your race cars and you'd be running low 9's/8's.

Trouble maker. Now you made me upset the Hemi guys. The new Gen 3 guys are almost as much fun as the old school Hemi guys. Just like feeling in catfish on a Summer evening.

Lol. Ya its my fault

I'm looking for 1 or 2 Gen3s right now.. I'll
put one in my 38 Ply and maybe one in my
Rampage if I can make it fit which will be
close

I have a lot of 340-440s sitting around, but I'd have to send most to a machine shop, buy better heads etc. It would get expensive pretty quick since all I have is stock parts.

I want to do a turbo 5.7 for my bevedere. I'll make headers, buy an ms3 system and so on and go run it, if it blows, I can go buy another 5.7 for 1k or less and do it again

Things are strange in Pittsburgh

Some of us aren't as uptight as others and like to have a little fun. Old school Hemi guys are a little boring and the Gen 3 guys must be too. Lmao.

Compared to you, Pittsburghracer, I am a good gen 3 racemotor candidate. I have NO spare parts for my 528, but i do have mechanical fuel injection that only requires a mounting bracket for the pump and a manifold, and have acquired Apache heads complete ready to run, a 3.888 crank, early 5.7 core motor, good rods, SRT exhaust and complete intake system plus a Helcat blower assembly in need of a front bearing.
It would be cheaper to build a 380 inch gen 3, and with the heads flowing 340 cfm right out of the box I would think 750 hp would be a piece of cake. Better yet sell the crank and rods and go as big as the 5.7 will allow, have the heads touched up a bit and be within a tenth or two of my current motors performance for a LOT less than I have in that piece.
In the end, it really is more about what we like. With your stash, a garage sale would get you enough cash to fund the project from what it sounds like. The fact that you posted this says you might,, some day.

You are never to old to try new things but honestly I haven't even raced a car with a big block since my wreck in 2010. Its been kinda fun playing with some of this small block stuff. Now with the heads-up car hitting the track soon (finally a big block) I have a whole bunch of learning to do. Nitrous tuning, progressive, Grid, suspension tuning, and what-ever other new hurdles come up. I will be buying at least a set of W7 head cores for a 48 degree build because of the Jessel rockers, intake, rods, pistons, and block I picked up at give away prices, but that another day down the road.

Brand loyalty has it's place, but not if it prevents you from completing a project.
An LSX will do anything a G-3 will do for 1/2 the money.

That's nice. Why don't you start YOUR own post and tell us about it. Please do, I'm all ears.

I agree, if money is all that matters, then buy/build GM and be a quitter..............

I think most here are aware of the LS platform's potential. So what does it have to do with this thread? If a LS floats your boat by all means build you one.

Live in the past with your purple shafts and 906's
Gen 3 is the future like it or not
40 years in technology advancement superiority cant be denied
Crank up sitting on the dock of the bay and build your antiquated 440's

Dick is the first thing that comes to mind.

Not everyone wants to run modern based builds, I dont myself but could at some point.

I watch the Gen3 people do things with all the modern gear, ign, fi and see some run a dizzy and a carb, its all about ones preference.

Even the baddest ls combo around sooner or later will get one upped by another build weather a ls or import or ? for that matter.

Most of us pick who or what class we race in, mopar guys generally dont take a knife to a gunfight.

Weather a Gen3 or Ls a well built, well thought out old mopar can still catch a ray of sunshine from time to time.

The past isn't half as bad as the future. All the gen X, snowflake cuckold males can't bring anything but a quicker end to the Republic than even I thought.

Gen 3 Hemi doesn't fit into a-body cars very well. That may have changed, but the first guys doing it had to work at it iirc.

If you race frequently it seems smart to stick with whatever combo you can afford to keep running long term.

I have not been to the track in a few years, but the local Mopar guys never seem to be the ones who can make all the races for a whole year. Mopar guy blows a motor, differential, transmission, etc and they miss multiple races before they return. GM and Ford guys seem to get their cars repaired and are back at it the next weekend or two. Mopar guys here have fast stuff, no doubt, but at the end of the year it's the guy with the budget build 454 single four barrel 72 Nova that takes the track championship because they make all the races.

And your point relative to THIS discussion is what...??

Same with a SBC, BBC, and so on. Your revelation is no news flash.

But try to say focused and on point, so one is talking about the LSX.

*Footnote: If I had to build a Shivy, I wouldn't have anything but an LS/LSX between the fenders!

I am building a gen III because it is different. I have owned big blocks ( never a small block though even though a wound tight small block is a thing of beauty).

When I started to think about a new engine I thought about this with a Gen III:

Block that can take 1,000+ Horsepower? Check.

Heads that flow great? Check.


Still a MOPAR? Check.


Stroker kits? Check.


That ticked all the boxes for me, and I am very happy that I went in this direction. More parts are coming out all the time for this engine, we should embrace it ALONG with Big blocks, small blocks, and other generation Hemi's.

Sometimes I think Mopar people are our own worst enemies. ( myself included!!)

FLATHEADS FOREVER!!!!

Yup, I hear you. I have a 4" Merc crank in the garage next to a 59L block and some 906 heads. These are weighed down by a couple of pairs of LY rods. Oh, yes, the SU359 intake hanging on the wall next to the 283 chevy 2-4s intake. None of it's worth a crap anymore.

I must be living in a different world, though, because the last time I saw a GIII for $500 or less was about 10 years ago, when they were having teething problems. My local Craigslists are fresh out.

R.

Incorrect an LS-X is a formidable piece but the heads ain't nowhere near as efficient as the G3 offerings. J.Rob

Big blocks don't fit well in A-bodies either with out fenderwell headers etc.. For that matter small blocks don't really fit all that well either--we have just learned to accept all the compromises. I am SURE a G3 will fit in an A-body better than any of them with fenderwell headers and with zero concerns about sparkplug access to boot!. J.Rob

Well, I am considering going to a G3 Hemi and selling the 605 Hemi carb to pan....

Got hassled at tech the other week pretty good with my race car, and the car the Hemi is in, is not setup to go that fast legally like my race car. So I either need to fully cage the street car, which I really don't want to, or go a little smaller....A G3 would be perfect with a BES dual distributor setup...

Racing needs to go back to being fun and less of a hassle, at least for me.

I agree. Magnum stuff has gone away because SB fans had to have LA family for whatever reason.

Gen III is where I'll be heading next.

A 904 is a direct bolt up? Check.

Then that 40 year old block splits at the mains and you drive over the crank. 😳

In all my 8 second passes I split one block and never found it till I took it apart after 275 passes. (no concrete, no super plate) Never leaked a drop of water. Now I would be smart enough to at least have a diaper wrapped around it like I have on my small block. Ballistic and heat resistant for the best 250 dollars I probably ever spent.

Party poop! I was having some fun with ya...geez.

You gotta get up pretty early in the morning to get a pot-stirrer. LOL

On my hemi, the headers go right in from the bottom. If you had to take the starter out you will hate it but easiest header install ever.

I hate hearing you can build a chevy for half as much. I port LS heads every day. Chevy guys are just willing to spend money. They work on their junk harder. They race more. They blow there junk up alot and do it all over again

And I really dont know of any faster than mine is on motor. Comparing apples to apples

My friends LS7 makes a little more power than me but Im a tenth quicker at the same weight

There's so much truth in both of these post.

G3 would be perfect with a BES dual distributor setup...

Racing needs to go back to being fun and less of a hassle, at least for me. [/quote]



Agreed.

I left this hobby back in 2007, kept about 50% of the stuff I horded over the years. decided to get back in to it, and IMHO G3 hemi is the way to go, great power to weight, good fuel mileage
If you have a #s matching 440 car, Hemi car, hell even a 340 dart, I say stick with what you know, my 68 Hemi Road Runner is going to stay GII , but if I find a S6 318 maybe even a 383 Coronet/Satellite, I'm going G3,
Some one here said Mopar people are our own worst enemies, that's so true,
Past is good to learn from , not relive
I love my Lil Red and Midnite Express trucks, and those will stay 360 and 440 powered, but if I find A Lil Red basket case, I won't think twice about tossing a G3 in it,
in the end, only you have to live with what you chose to spend your money on, any gives you crap remind them whose name is on the title.

I certainly won't miss reaching around hot headers to remove my spark plug to check/change them when I do the 5.7 swap.

As far as lsx motors go, I've built them and gen 3 hemis... to me they are pretty similar and cost wise most parts didn't cost much less for the ls1.

But I got all the regular stuff already, at no cost. Now you start from scratch. In fifty years I can count on one hand the stuff I bought new.

Gen 3 Hemi's SUCK!!!

Lol. But the girls at the car shows dig them.

Nothing wrong with that.

Yeah you can move a lot of CFM thru them stock

Rumor has it that SixPackguts G3 car is so fast he can pull 8 plug wires and still run 9s!

Ill agree. Our Challenger seemed like it stayed in the shop. Needless to say it got traded off.

I'll stick with the old school junk. Regardless of what anyone says, the Gen 3's are more expensive to build and install. The headers, oil pans and engine mounts they require are not cheap. The rotating assemblies in side the junkyard pickup truck 5.7's are just that, junk. For a fun, 500-600hp street car, an old school RB build can be done for a fraction of the cost without roller-this or stroker-that.

And it's a small block. Too bad that head won't fit on a 440 to 572 ci big block. Now we talking power.

Aaaaaa I think we have heads that flow SLIGHTLY better than that for big blocks. Heck the W8-W9 stuff that Brett does is impressive as heck.

But you can't pick them out of a junkyard, that's the beauty of a G3. You guys that have stuff for a BB stacked like chord wood it would make no sense to build one. Starting from scratch it's still a wash

I think, that's the deal. If you build good power with the old stuff you need an aftermarket block usually and availability is sketchy. So it will come down to what's available. Waiting months for parts that might never show up doesn't work.

Some people you'll never convince.
I'm actually surprised they are even on the internet.
Watching their black and white wooden cabinet tv sets and adjusting the rabbit ears for reception.

I updated to one of those electronic rotors on my TV antenna. It works GREAT!!!!!!

i remember a few years back BES did one for the engine masters contest and was 80hp over the LS piece.pump gas hyd cam 700hp ish pretty impressive from what i can remember and im sure he would have did a LS motor if he knew it would be a winner.340 Rick has one in his 70 chally runs 9.6s i believe also pretty mild build.

Hardly anyone seems to be doing one for racing....Ain't seen one up close yet...

Oh i forgot to mention Dave S local guy i bought 512 RB off a few years back that he replaced with a boneyard build 5.7 stock 6.1cam and heads with single turbo 3.23gears that ran 8.9s.he is also a member here if you want specifics on his build.

If that was pointed to me I'm not interested in a 8.9's power added build. My 512 will cover that with no adder, but thanks for the offer. Now it only comes down to was that number at one of the mineshaft east coast tracks or inland.

that wasnt directed at anybody just to point out that they are deffinately decent pieces to work with.tell me more about this 8sec 512 very interested!!!

I know you want to play hard core that you wont
change.. but that 8.9 is with a STOCK engine that
a guy put a turbo on.. your car is light.. what
was his.. you better learn to open your mind a bit
or not

His car must weigh 2000 lbs to run 8.90's with a 512 rb

If I remember right he is running 2400 or
just a bit more.. still a good running car

8.90 ET at 2400 lbs = 672 hp. 672hp from 512 cubes.....Not impressed.

Who in the heck said the car weights 2400 pounds. Lol
I wish it did because then we would go even faster. Like I said you will never see me driving a two ton tessy. My street day's are over and I'm to young to need creature comforts. But this is a story for another day

Having built and raced every engine Mopar has ever built hands down a GEN 3 is the best bang for the buck. Using the example of 700HP show me a stock BB/SB or really for that matter a stock Gen2 head that will support 700HP. You might get there with a Gen 2 head with work. A 700HP big block even of you start with a block you already have will cost you more. If your starting from scratch you need
Headers good headers are the same price for either
After market oil pan I have yet to see a stocker that will support 700hp
Heads --You can use stock 6.1 or apache heads
Rockers---You can use stock gen 3 rockers on a 700hp build
Rotator is the same money
Machine work is the same
No brainer I built one and the only reason I would build a BB or Gen 2 hemi now is if I would want to go NSS racing again (which I do) but I hate the thought of building another BB!!!!

betcha theres more $$ in that 512 than the turbo 5.7 and its around 3100lbs.im convinced gen IIIs are not the way to go LOL

I lurk over on the Moparts gen 3 area because believe it or not I am open minded and enjoy reading and studying before I leap. As for costs I have 2800.00 in my mega block ready to assemble, 2200.00 in my rotating assembly, and under 1200.00 in my 440-1 heads with Harlan Sharp rockers with upgraded 2.250 valves (I will probably go with a set of T&D rockers if valve to piston permit). Indy intake was in a package deal and 500.00 in the alcohol toilet if I go that way. It adds up but still what I consider budget build as I shy away from some of the "ragazine" tricks that drive up costs. But like I said my eyes and ears are open while you guys get a hints figured out. I can only hope that is a misprint on what a gen 3 guy said lifters cost in that one post over there.

Not sure where you find $1200 -1 heads with Harland sharp rockers or a $2800 mega block ready to roll hell just find a mega block worth building right now. This is why I will put a gen 3 stroker together and run 10.0 index vs NSS

8.90 in anything with doors n/a... I'm impressed.

Wonder if ptsbracer get lexan, fiberglass and holesaws as cheap as engine parts

IIRC he removed the glass doors from the car in favor of more "friendly" stock doors with roll up glass.

No kidding, and it takes a lot of work weather old school or new just seems a bit easier w/late model and EFI. I know I came off very strong and negative about the new stuff so my bad there, it's just a personal preference thing and there's no right or wrong until stubborn guys like myself and a few others make it personal. I love the positive and negative results I get from carbs and although messy and a pain at times, I just cant see myself on a laptop tuning. Hell, I cant even post pics here............... N/A Old school has been my goal forever so that's where I`ll stay and shoot for that elusive 5.99..............

If one did a graph showing age to what type engine, I think it would show real clear who likes what. Heck for the sake of argument, if either engine was free with all the goodies, which one then.

ack in his



Ya I could start a weight gain post. Between kicking my son out of the car and back in his, stock steel doors with stock wind up window, alternator, exhaust, R3 block, diaper, racepak and electrical upgrades, and a few other goodies I added 250-300 pounds to the car. Lol. I call it my old man car. Race it, drive it in the trailer and climb out the window, and go home. Matt went to take the hood off at the track last week and I asked him what the heck he was doing.

Lol. Thats how I am and exactly why I went g3. Hyd roller ftw

I'm exploring building a carb'd Gen 3 for my dirt late model deal... rebuilding a small block 383 right now.

Seems to me it will be cheaper than buying a Ritter block and W-2 or ported aftermarket heads. Plus the good Eagle heads are better than most any small block head and are on the shelf at my local dealer 6 blocks away.

The juice lifter deal is my only question mark... can they live for 25 laps on a 1/2 mile at 7,000 rpm's? The T&D/Jesel numbers don't fit my budget right now so solid lifters are pretty much a no go.

We'll see.....

Remembering back to when the 2.2 was the only "factory performance" engine platform, I see alot of humor in these discussions....We're actually pretty lucky to have anything, considering how small our overall volume is.

Amen brother!

Thats me as I am old school top to bottom. But thats just me as I love what I grew up with. Even on brand X as if I see a nice 69 Chevelle SS 396 and see a newer LS under the hood its not what I like to see under there as I want to see a 396 or BB Chevy under its hood. And as I say thats just me. Nothing wrong with anyone going with a modern eng in their old muscle if thats what they like. I like the NSS racing alot and like to see what eng belongs under their hoods as thats what floats my boat. But the new eng will run good and I dont knock anyone for building what they like as you have to build what you like.
I honestly think many of us including me were really surprised to see the muscle cars return with all the power they have with the power adders as I think most like me felt we would never see anything like this from the factory again after the muscle cars died in the 70's. Bottom line is new or old Mopar they are all Mopars so we should like them all as I do. I just prefer old school for myself. But there is alot of modern parts now for the old school engines that help them run alot better also. Ron

there was a member here that built a GenIII for a dirt modified here. Seems they had some bearing probs, but corrected some oiling issues and it worked.... can't for the life of me remember who it was.

I have only had decent flat top pump gas BB's. I have a decent flat top stroked Gen III now and it's a no brainer. This 45 yr old is done with the old stuff, unless I have something fall into my lap and the budget dictates.

CHAPPER did, and it took an aftermarket crank to get to live at 8000+ and a 13qt pan iirc.

you know the old Hemi guys in the 60s felt the same way about the 440's and small block Chevys
Time has a way of moving forward, and it's a good thing that some people stay in the past....

Yep, I think it was the 6.1 crank's cross drilling that caused oil starvation

I don't think he used a 6.1 crank, IIRC he used a 5.7 crank.

I keep seeing the word cost thrown around. What's the comparative ballpark dollar value for a guy starting from scratch?

No friend deals and nothing sitting in garage, buying aftermarket stuff at full price, blocks from junkyard or Craigslist, assembling everything himself except the short block, and also paying a shop for machining... what would be the cost to build a turn key 700hp BB vs a turn key 700hp G3 street engine, with headers and motor mounts to fit in a late 60's B body?

Ohhhhh boy. This should get good.

For your 700 hp Gen III you can use junkyard stuff, sixpackgut would be one of the guys to answer this question the best.

Your shortblock cost will likely be about the same because it will all be aftermarket rods, crank, pistoms, etc. The top end is where the G3 will shine. Factory heads, lifters, and rockers. The intakes are still stupid expensive but your still cheaper with a G3 IMO.

When you get to ignition for the BB you need to buy, a coil, a distributor, an ignition box, and plug wires. For the Hemi you can use your stock coils and get an MSD Hemi 6 to handle everything else.

Your headers and mounts will likely cost about the same for either engine.

And we're off! This is a honest look, apples to apples for the 600-650 HP target. Of note, one can find Eagle heads cheaper than my listed $750, just threw that number out there. There is also a new single plane Arrow intake that hit the market for $550. Of course there is more than one approach to the build, these were comparable parts and their costs:
