I like this build......It would suit me all day if I could do a G3 with the same results.

You can get close cubic inch wise- I believe the newer aluminum blocks can go to 468". Thitek heads would probably get you close to your goal as well.

Show me someone who has built one after all these years without exotic parts...Thitek heads, this guy used regular Eddy heads, made 1000hp, on a small block at a reasonable rpm!

I have a set of Eddy heads here on the shelf assembled by Thitek, show me how to get anywhere near that level. Lets start with 475 cubes!

The chevy guys now have 1000hp NA small blocks and so do the Phord guys.....Where are the Mopar builds?

I found the heads and intake right on Summit racing website.....

Those heads are Edelbrock Pro Port heads basically castings with seats. They start at $8200 complete at BES. The intake is a split CID or Mast intake. A Hemi can be done if you want to spend 45k like the guy who owns that LS. I GUARANTEE there isn't one off the shelf piece in that engine.

Your probably right, but the heads bare are $1400....I want to see some G3 builds like this.

LOL @ comparing a G3 RPM head to a LS-R head.
Thiteks are not at all exotic when compared to any Pro Port head

Is there even demand for a 1000hp NA 3rd gen? All of them are boosted and the one in the video eventually will be too.

Just looked up those heads "starting at $8200" laugh2

Must be for some odd ball NHRA class

My comment was simply that the Thitek "BEAR" cylinder head is the best available, unless something else has taken it's place by now. I did not compare the Pro Port head to the Thitek. I also did not mention other's cylinder heads that were ported by Craig, I was talking about the actual Thitek head.

Thank-you.

That in itself explains 99% of the ls crap I get to listen to from the slack-jawed Meatheads that think the ls is the Second Coming. They thought the 350 was the Second Coming too. laugh2

A friend of mine is running an '07 Charger with an aluminum block 449ci with apache heads and a drag pack intake manifold. Dyno'd at around 850 hp and runs 8.80 in the quarter. Engine is at the engine builder for a refresh and a different cam. Expects up around 900 hp when he gets it back and wanting to go low 8s. Doesn't want to go lower than 8s so he won't have to put more cage in it.

Oh, and this is NA and no NOS (and no BS) lol

I never implied that you did, I was laughing at:

They are $1400 because they are not USEABLE as sold. They are a head porters casting to customize as required. Thitek sells the same thing and I'm sure Vizner or CFE could get 1000 hp flow out of them. Its just money.

That LS is like putting a P5 head on the G3. It retains zero stock layout and parts. The thitek is a stock replacement head.

The market for that type of head for the g3 is too small. The amount of people who want a 1000hp na mopar small block or G3 is very small. Power adder makes it alot cheaper and less maintenance for 1000hp.

Yes, they are canted valve like a BBC. Everyone wants 1000hp NA till they realize the maintenance involved. Power adder is the way to go now. High Hp and very little maintenance. I have a customer with a 1500 hp single turbo BB Mopar that he's been running for 3years. When I freshen it it looks like new inside. Thats what you want. Not some Peaky high rpm motor that has a power band like a 125cc dirt bike! Those are purpose built class engines.

I agree the G3 is better suited for Power Adders but if you got to have NA call up Barton.
Their gen3 426 ss hemi makes around 950 hp for only $50K. I am sure he could get over 1000hp on an unrestricted combo.

I never heard of an LS-R head until seeing the video. It sure doesn't look like a normal LS head

Ls-R is a canted valve head like the Mast Mozez head. The are very nice pieces.

Thanks that make more sense after reading the first few posts I was going to build an ls runaway. I thought that was impressive for an inline head.
It still is 1000hp@7000rpm

And Capable of flowing 435-450 CFM in the right hands, these LS-Rs flow between 435@.700 and 440@ .800 and 450 @ .900
Thitek heads can get close in the flow department.....Edelbrock G3 heads will never get there, they are lucky to get in the 390/400 range@ .700.




That 475LS is close to a 55k as tested . the block is 9.75 Deck height....... 4.155X4.375 , and a LOT of internal work to make that 4.375 crank work in that block, fitting a 4.10 stroke crank is lot of work....... it's also uses 6.46 C to C rods, Pistons are 1.10 Ph height , Rod Ratio is 1.47 . uses 2.25 Intake valve with a Valve to bore ratio of .54 ....just right for canted Valves.

Crank is Callies LS Ultra Billet 8 Counter weight 4.375 stroke. the off the self 4.0 stroke version of that crank cost $32XX, you will pay less for a new Callies G2 Hemi block then you will for that 4.375 stroke crank shaft.
Block is Dart LS Next Tall deck $4700......which is still less then the crankshaft used in that build.
the CID Intake was close to $1500 and is a custom piece at this point.
lets not get into the rocker gear...it's about the same as anything Reid for a G2 Hemi.

Biggest LS I've ever done was a 481ci 4.185X4.375 with CID Oval port LS heads with raised Exhaust which flowed 425@.700 and 435@.800 ....total cost in parts was 38k ...again price for the PARTS was 38k and made 990hp with .8XX/.7XX 255/260@.50 on 112oct



the Biggest G3 I ever built started out as a 2014 BGE block it was machined to use Darton LS Sleves , and hard blocked for the 1st 2.5 inches..... 4.20 bore with a 4.30 stroke crank for 476.5(lets round up and say 477) 6.125 rods , so rod ratio was 1.42 pistons were Hockey pucks 1.00 .....it had Thitek heads and .630/645 240/245@.50 cam 114CL made just shy of 875 on pump gas @ 6800 pulled it off the dyno , sent the crank and rods out to be magged and the crank came back with stress fractures.
now to get the 4.30 stroke I had to offset grind a 4.25 K1 crank, to 1.88 journal size. Lots of grinding to get the crank to fit, the oil drain cross tube on the passenger side rear of the block had to be taken out BIG clearance notches Everywhere... .total parts cost was 14k ...yes 14k , Block was 1300, Crank was on sale from TH motorsports for $650, rods were Pankl 1.88 BE bore with .797 pins .rods and heads were the most expensive part of the build roughly half of the cost , the darton sleeves were a buddy buddy deal and cost about $750 , the machine work was costly had to sign a waiver to get the guy to do the work....I honestly don't blame him. I hard blocked the bottom of the water jacket to insure stability didn't want to take the chance of the sleeve moving around with that much side loading.....Pistons were some where between 1000 and 1200.

at this time the aftermarket parts to build the Equivalent G3 Hemi to this 475 LS(X)....do not exist......and considering how 90% of the G3 performance "enthusiast" lean towards Boosted applications and the EPA's war on anything "performance" I doubt they will exist.
At this point we really only have one aftermarket block which you can get in a 9.75 deck height if you go solid billet with no water jacket. but if you want a water jacket then your limited to a 9.28in deck height. which limits us to a useable 4.25 inch stroke...... ......and you can not make enough clearance in the stock blocks to use a crank over 4.3 inches. realistically for NA we are limited to a 4.165 bore with the BGE blocks , 4.125 to be on the safe side. Now the 6.1 block , Darton makes a sleeve that will go to 4.165 but the 9.24 deck height limits stroke to a max of 4.25 and here again you end up having to use a 1.00 Pin height to fit it all in the cylinder which is fine for a 500mile Nascar engine , lousy for the boosted crowd. and not daily driver friendly.
