That seems like a good package. If it was me I'd go ahead and build a 572 since it wouldn't cost anymore money. Then use a flat top piston and you'll still be right at 14:1 or so. A 4.5 x 4.5 engine with flat top pistons and -1 heads should make excellent power and be fairly economical to build. All of the parts are off the shelf. There shouldn't be any problem making 850 to 900 hp with that package if the engine is built with some care.




First of all, I don't want to step on any toes here, but why in the world would anybody use -1 heads when you are building something like this? The max HP, and I mean max is 850 with the -1 heads, and that's an exceptional -1 motor. And it doesn't cost that much more for B1 originals or even 572-13's, but it will cost more for the paired rockers and all of these parts are off the shelf too. Someone here even said they had a set for sale reasonable, and there's room to grow with the B1 head. A mildly ported set will make 850HP, and I mean a cleaned up port match and good valve job. And nobody I know that races is ever happy with what they start out to build. The Predator is a good choise too, but I don't know if you could keep them at 850HP. And the 572 makes sense because the cost is the same for a 4.500 stroke crank or 4.250. Now go ahead start telling me I don't know what I'm talking about and how -1's make 900+HP and flow 390cfm. I have used -1's, B1 originals, stage 6's, 452's and 906's steel heads and now predators. They all have their limits. But if you are absolutly sure you won't ever want more HP, then use the -1's and build a 540. Just sayin, nobody is ever satisfied, at least nobody I know.

The title of the post is economical so I assumed that ment he wanted to keep the price down. If he has a $30K budget then sure, step up the heads, add the aluminum block, add dry sump, etc. It is all good if the guy has the money. He never said what the budget is so most of this thread is just jibber jabber anyway.

There's no economical way to go 8.50's in a 2800# door car with a NA Mopar..

Unless you buy a used motor..

The problem is that the word economical is useless. Some people can't afford $50 entry fee to go racing, others buy a new truck and trailer every year just because they can.

So my assumption was that the guy was willing to spend $25,000 for a 850 HP motor. If his budget is bigger than that then sure, step up the heads, add the KB block, etc.

Now if he thinks he is going to make 850 hp for $10,000 then there is a disconnect.

Indy sells 900 hp crate motors so it is fairly easy to write a check and buy a bullet. Some of their crate engines use -1 heads, others use the 572 head. The -1 headed motors make 800+ hp so it is very much an option.

Predators economical?



All this talk about aluminum blocks, portred B1s or indys and roller valve train in this thred dosent sound very economical eather? What your going to spend on the predators up front, you save on porting and roller valve train to meet the 850hp. goal.

Any engine that is new making 850HP, whether it's maxed out or has more potential is going to cost $20,000 with a steel block. You could build a 950HP, but the difference would be the quality of the parts, Eagle crank, eagle rods, comp lifters, etc. If you buy used, have some spare used parts, or are willing to buy used parts, you might save $5000 for something like that. But an aluminum block will be an additional $3500 after machine work. Oh....and I would say this is if you put it all together, no dyno, unless you know someone that is capable. Good luck on your build.

just asking but are you saying once you spend $5000 on an aluminum block you will be spending another $3500 on machine working totaling $8500 before assembly? anyone wanna buy my world aluminum block with about 500 miles on it for $4000 all machined up(all arp hardware?)

Where do you get that? Let me explain....it would cost an additional $3500 over a steel block for an aluminum block with all of the machine work done. And a person could save possibly $5000 opting for used parts over new. Is that clearer?

The Indy crate engine pricing could be useful for this discussion.

http://www.indyheads.com/images/price2011.4b.pdf

An aluminum block upgrade is $1800 so that is a decent deal. The 930 hp 572 motor is about $22,000 if you upgrade to the Ti valves and get the Callies crank.

The cheapest deal to make 850 hp looks to be about $18,000, but some of the parts used to get the price down might cost more in the long run.

As pointed out earlier, this is for a race gas motor. If you want to run E85 or pump gas, then the price goes up. Of course, if a person already has some parts sitting around then the price could go down.

Guess I will chime in here. I ran my junk last month in 5700-6000' of air and only managed an 8.57 best. Granted that air sucks and as pointed out trying to find a convertor that works with my combo has been a challenge for sure, yes #6 is in it now and no better than #5. Trying to get the engine happy at the shift has been a huge issue for me for sure. My car cannot fall out of a tree quickly either, it 60's like a pig, best ever has been 1.17 and that was an 8.0 at 169 in 600' of air. Granted my car is not geared for quick ET's, I am a throttle stop racer so run a conservative gear in the car and a big tire.

IMO building a BIGGER motor would make that an easier task. My engine makes no torque and has a somewhat peaky power band. Trying to get someone to build a convertor for a BB mopar and a glide that works in the RPM range I need has been an issue.

My junk weighs right at 2900lbs race ready. If you want to run S/ST and get the MPH once again I'm gonna say build it BIG. I have been 10.90 at 158 and change. More typical at seal level is 156ish and up here 153ish is typical.

I had an 850hp motor in this car before the current bullet. It was a 572" Hemi that used to be in it. The car wieghed just over 2900lbs and went 8.70's in good air and 146ish on the stop at 10.90. If you really want to run 8.50's in the heat of the summer you had better plan on making more than 850hp at 2800+lbs, just saying.

As for combo, if this really is your goal build it as big as you can afford. Put the best heads you can afford on it. Then let her eat. As pointed out in this post, running 8.50's in the heat N/A at 2800+lbs is not easy. If it were you would see more cars doing it. Most of the door cars I see running anywhere near what I run weigh a LOT less than my car and generally have a whole lot more engine.

Maybe MoparBillys apporach would be better. Build a good motor that makes 850ish HP. Put a fogger on it and spray it to run 8.50's. A simple little 150-200 shot shoudl be more than sufficient to do this. IMO that is about the best budget bang for the buck out there.

Umm my KB block was a lot more than $5000 by the time was all said and done. By the time is was set up for pushrod oiling, the lifter bores were bushed and the 55MM cam tunnel was done the bill was a good deal higher. If you want the best stuff it comes at a cost..........

X2! Excellent idear. Aftermarket block, 540" or so, some EZ or SR heads with max port volume that use 'cheap' rockers. Use a nitrous friendly and gentle roller cam. Should get you 750-800 HP, spray the rest via fogger.

For a budget build, I would still start with 440-1 MCH cnc ported, and as far as rockers, with a mild cam and the correct springs for that cam, you can get lots of runs with Indy rockers before they start to fatique and break. Springs should still have 20-30pounds more pressure than recommended, for extra safety.
The same goes for B1 originals, with a mild cam 0,700-0,750 lift, the Dove rockers will have a pretty good chance of lasting a couples of seasons. With mild cam, I mean not to go crazy on the 020 and 050 duration. ( specially on the 020 value).
Fast ramp cams eats both springs and rockers.
540 for 440-1 MCH porting and 2.25 valves and
572 for B1 originals, also with MCH porting would be a good start IMO.

T&D rockers and 2.30 Titan valves would definitively be nice, but not economical, as this thread is about.

IMO running nitrous in any index class is not a good idea when consistancy is your best friend

True, but it is definately the cheapest way to go. And as mentioned several times....people have limited cash....me included. The only thing NOS would require is a good aftermarket block.

I figured someone would say that. Well from my experience that is simply not a true statement. If the saem care if given to ensure all aspects of your nitrous tune remain the same as you take with the rest of your program I blieve you can be very consistent with it. We are not talking 4 stages and 600=hp here, it would only require a small shot to achieve the goal he is after and if done properly can be deadly consistent.

Looks like we'll have to agree to disagree.....not to mention you can only run nitrous in any of the super classes if you are running a turbo diesel....lol.... at least that was the ruling last I knew

I agree with the poster who said -1 make no sense, they really don't. 572" makes the most sense, 604" would be even better. There's a Callies 4.75" on RJ for $800 and you'll be spending money on getting anything other than Winberg/Bryant/Moldex/etc cleaned up and sorted right anyways.

B1's are the baseline I'd look at. Just bought TD's for my B-1 and they were $1100'ish with shafts. That's maybe 300-400 more than the Koffel/Dove stuff. If you can't find that $ for a build like this, stop now The MC's are probably a decent step-up if you wait for the sales or find somebody moving up. I'm going E-85 at 13.8:1 EFI at a lot less cubes and I expect to be around 850, but I'm running drysump. There's no really significant price difference between gas and E-85 if you haven't bought stuff yet. You need more fuel pump & injectors(for me), OK, big deal. The cost difference in this budget is pretty insignificant.

It seemed to me that the canted valve stuff was a pretty big $ hit over any of the B-1 wedge stuff. Unported Preds complete were $11k+ and while they're a real step up over any wedge head even unported, that's at least $4k more than I have in my B-1's. S/F.....Ken M

Thank you for all the suggestions. Keep them coming, may try to do something identical to my Dad's setup. 572 aluminum block, with -13's IIRC. I really don't care for the tunnelram setup, personally I am thinking either a toilet or injector hat setup. By budget build, I am not necessarily thinking of a dollar figure, but mostly what do you trust used versus better to buy new kind of items. Really want this engine capable of running Nitrous as a catch up/make up bracket means only. maybe something to use if I am borderline for making a quick 16/quick 32 field. I know this is gonna be costly, but wondering what I might need to expect.
