Hi All. Just wondering what 4.75 stroke 4.50 bore combo's we have running here. Interested in et's, tyre, gear, race weight, shift rpm and finish line rpm mainly but combo details would be great too. Thanks in advance. Tig

I have a 604 Predator engine in my dragster, but haven't run it yet. I'll know next year when we go to Las Vegas in Feb. It's a 604, 15-1, 1 1250 carb, Marcella sheet metal intake, made 1117 on gas. If it weren't for the Predator heads flowing over 500 cfm,I would have just built a 572. Everything for the raised cam block is $$$$$$. PS. I posted the dyno session on here a couple of months ago, if you wanted to do a search. And B1 Johnny had Best machine build him a 588 PSO that made over 1200, if IRC.

Motor will be a wedge head with the bore and stroke previously stated. Rod journel will be the 2.200 size as I've heard this will work in a standard cam location block (steel rods btw) I guess my original question would have been more to the point if I'd asked if going from 572ci to 604 was worth it. However I'll be upgrading the heads (would like a best machine cnc port and Ti intake valve). Change rocker ratio (1.6 to 1.7) also and maybe go to a tunnel ram. Thanks.

Unless you plan to move up to PSO's, Predators, or B1/TS heads, I wouldn't do it. 572 will be plenty of CI for those heads, and you can run aluminum rods if you want to with 2.200 crank pin with no clearance issues. With the 4 3/4 in stroke you need a special pan, and are limited to steel rods. JMO.

I have considered PSO's  but I've got $2500 in a set of custom headers for the -13's. Would they fit the PSO's?

Oops, not the PSO's. It's the B1 MC's that I thought might fit  Thanks for the advice, I'll probably just do everything to the 572.

tig, my 572-13,s only flowed 388@.800". i got them from indy with their cnc work done. they claimed 410 cfm to me too.
when i called indy and talked to ken, he said to flow 410 cfm, you needed to thin the valve margins and blend the seats. he also said that would reduce reliabilty. mine is in a street car.
their claim is just a marketing ploy, to buy their heads. someone told me theese heads would'nt flow 400 cfm with the valves out...i'm doing a 588-604 myself. i will be using b-1 mc heads on this one....

My hand ported -13's flow about the same, around 380cfm. Got them untouched from Indy back in 2001.
I think Best Machine have a cnc program for these heads that would take them to over 410 cfm with a 2.35 valve IIRC. It was these I was thinking of.

I agree. 390 is the end of the road for that head.
A really good W8 will make the same power.

I guess to keep it legal in NSS even though my car is a 1971. One day I'll put some big carbs on it.
So no one else runs a 604"? Wedge or Hemi? I know HemiFred has one, his motor and car build was highly documented on here. I've seen pics of the car at the track, maybe he will chime in with some performance numbers.
Anyone else?
Thanks...

Have you ever thought about taking a bit of weight out of the car, i dont mean chopping it around, just bolt on stuff.

So you guys are saying you can use the 4.75 stroke crank in a standard cam location block, with aluminum rods? I don't think so. My 4.50 stroke needed clearancing on the rods with a standard cam block, 2.325 pin, with GRP's. Even at 2.200 it would only be .125 more clearance.

Perhaps you can make a 4.75 stroke fit with aluminum rods and a 2.200 pin size, but you would need to take a lot off in a crtical area of the rod, IMO. And the question was, is it worth it for 572-13 heads? I would say no, and it would add a lot of expense for very little gain. As I started to say, you can do anything you are willing to pay for, but the expense involved is not worth it. If you want a high horsepower 1100+ combo, contact Pete at Best or Diablo. They have proven combos for sale, and that's not as easy to do as some people try to make it sound, at least not naturally asprirated.

hello tig ,i ran a cast iron head 604 hemi in my savoy a few years ago, great street strip combo, car was 3800#, 29.5 11.5 15 hoosier qtp., 4:10 gear, ultimate 9" tc 3500 stall, tti 2 1/4" headers 4"collectors, 4" x pipe exhaust to rear of car, single dominator,barton intake, cam was roller 112 lobe sep..670 lift etc.
the car would go 1.40 1.43 60' on the dot's, run 9.80'sat 137.00 all day long,once i got it in the car it needed very little maintenence,
only problem i had was after i bought the junk indy legend heads,the 510 cfm adv. was about 10% off low lift was ok although. the heads had two chambers machined out of place and the pistons hit. naturally russ did not want to make good on anything.cant understand how indy stays in business.

That sounds like a fun car and.......
With Eric's Stage V heads, in multiple configurations, there is absolutely no reason to waste money on lesser products.

I have a very well worked over set of 440-1 heads with 2.300 intakes, which are the same casting as a 572-13 with the following exceptions. Moved exhuast valve to allow a 2.30 or 2.35 intake valve. rolled 2 degrees for a touch better breathing. Those heads have been a touch better at making power over a 440-1, but not a lot. They just don't have the port csa or volume to feed a BIG motor. My guess is they will be pretty much all done increasing power by using a 572 cube shortblock. I run 528 cubes under my 440-1s and I don't see many guys running that much faster per weight carried, and with 572 to 578 cubes.

Thanks for all the replies. I'll outline the dilemma. I want to go faster, I thought I could do it with more cubes and the block and top end I'm using now. Plan was to buy another set of -13 heads (since then I can use all the other stuff I have) and get them cnc ported. But I was going to buy another set of heads anyway, Predators are out of the question I think they'll work out too expensive for me, and I think the same for the B1 TS. Not sure about PSO's though, I've no experience. Should I keep developing the 572 or go to 604.  Seems like the heads I have are holding me back  Also can anyone tell me if headers that fit -13 will fit B1 MC's? (or PSO's)? I don't want a Hi RPM race gas motor. We've gone 6.1 @ 114 1/8th 9.57 @ 142 1/4 @ the weight in sig. I shift @ 6500 and motor goes to 6800 at the stripe. 4 figure HP would be nice since we think we're around 850hp given the times, MPH and weight (Cars been weighed on 4 scales now all within 40lb). Thanks again. Cheers. Tig

Hard to comment without understanding what your goals are for your car. Do you have an ET or MPH goal in mind ?

You also want to keep the budget down.
I would get the best cnc B1 originals with 2.30 Tit. valves with PSI or equalent high quality springs with 360-400psi seat pressure. Cam with 0.850 lift, T&D rockers.
Stay at 572cui square engine.
Start with single intake for an possible 1000hp with the right parts compr. and cam and later upgrade to sheet metal intake for a 50hp increase ( twin domin.)
Staying with 2.30 valve at 572cui will keep the rpm lower.

only problem i had was after i bought the junk indy legend heads,the 510 cfm adv. was about 10% off low lift was ok although. the heads had two chambers machined out of place and the pistons hit. naturally russ did not want to make good on anything.cant understand how indy stays in business.
I have bought 5 sets of heads from Indy. The last set was SR 295 CNC'D from Indy. I paid extra to have them mill the heads for a 63CC chamber. This was approximately 4 years ago. At the same time I put a roller cam in the motor, same as my other 500" motors, this motor never performed the way it should. I always thought it was down around 75-100 hp. I tried everything, including asking for help on the site, just gave up and drove it as is. It ran fine, just low on power. I dropped a valve, a few months ago. so I had to rebuild the motor. Come to find out, the heads that I bought from Indy and paid to have milled, were never milled. I never checked the cc of the chamber when I got the heads, but did during the re-build. They were around 78CC, it made my compression about 9.5 - 1.
When I called Indy and talked to Russ about this, I had the receipt, and he said there was nothing they could do about it, since it was a few years. He also took tone with me and it seemed to me he was implying I was making it up. I have purchased over $40,000 worth of Indy products directly from Indy. You would think that would mean something to them. I will never buy from Indy again. Everything I have read about them appears to be true. My next motor will have NO Indy parts. I also do not see how they stay in business.

Boost sounds like the best plan to me. I have a 572 B1 that is pretty much described above and I am not sure that it would meet your goals for your car but it might be close. I would not go to the 604 with the -13 heads, but what do I know I have not made a pass in a year and a half !

Tig...to go 8s and not use nitrous, I'd go w/ a procharger. That's exactly what I'd be doing if I had the money. Use your current motor, just boost it. You can make STUPID power w/ a procharger on that motor of yours. I prefer the blower over a turbo just for simplicity. Just my

At 3830 lbs to go 8.90s consistently, you will need close to a solid 1100 hp. That is a bunch. The smallest head I would even consider would be about the best ported B1Mc out there, or Predators. The weight is just killing you here. If you could shave some weight off the car and get it down 200 to 300 pounds, you can get by with the B1Mc heads most likely and not have to go with the predators, which would probably have to be bought new. A used set of B1Mcs with a good performance history is what I would look for.

You can run a 4.75 x 4.500 (604) and you can use aluminum rods, they must be the radiused Bill Miller version or equivelent. I have discussed this combo with Scott Koffel. He has built several. poppaj
I think its a pretty common combo, mine has GRP rods.
So you guys are saying you can use the 4.75 stroke crank in a standard cam location block, with aluminum rods? I don't think so. My 4.50 stroke needed clearancing on the rods with a standard cam block, 2.325 pin, with GRP's. Even at 2.200 it would only be .125 more clearance.
I am talking a Indy or KB alloy block with stock cam location, NO small baseline cam needed, It is tight but fits.
I can't speak for the other guys but our block will except a 4.75 stroke with a standard cam location. I would assume any other aftermarket block would do the same

How does it run?
At 3500ft corrected altitude in Las Vegas, it ran 7.38@179....so pretty good. It should be slightly faster with a non NOS cam and pistons. It's a dragster at 1850lbs.

I have the World block with the GRP pro series aluminum rods and mopar pin size. I run the 4.500 crankshaft. 4 of the rods need to be clearenced to clear the cam tunnel and pan rail.
Hi Tommy,
With the Miller alloy rods with a standard ground roller in most cases you end up with a hundred thousandths cam to rod clearance. That is with a chevy 2.2 rod journal. It is close and there is block clearancing that must be done. I will say if I were going to build one and did not already have a block I would go for the .250 raised cam block, it just would make things much easier. poppaj
Well, I stand corrected. I called my engine builder this morning and he said it would fit with 2.200 pin, like you and others said. I guess I just wouldn't want to clearance my rods that much. I don't even like clearancing mine for the 4.500 stroke, and we just massage them a little. But thanks for the info, good to know.

572 with 8.5to one comp and a f-2 procharger = 1400 hp on pump gas at about 14 lbs of boost makes a cool daily driver !!
