WHOS RUNNING 572-13 INDY HEADS - 02/15/12 06:28 AM

I have a 572 motor with 440-1 INDY heads and am thinking about going to a faster class and i am thinking about a set of 572-13 and i just would like to know if they are a real good head or the good and bad about them THANKS for any help .

I ad a set of solid -13 and looking back I would not do it again. The flow number were not very good. I think you can get just about the same out of your -1s.If you still want to change I would look into B1 or predator.

good luck

On a 540 I had a very good set of 440-1s with 2.25 Intakes..
The next Year I switched to the 572-13s on same Engine..
On Hemphills Dyno the 572-13s made 35 more HP over the -1s..
It also moved peak power from 6800 to 7300..
The 572-13s the power didn't fall off as fast past peak like the -1s. The power fall was gradual to 8000 on the 572-13..
I know the B-1 Stuff and Predator is Better but the Indy stuff put Me in the Power level I needed at the Time.

As mentioned with any large volume head expect the power to come at higher RPMs.We run the -1s on anything 572" and down and keep the power range under 7500 rpm for realibility.

For the money you will spend on a set of 572-13 I don't think you will get much of a bang for your buck. Like said well ported 440-1's with the 2.25 intake will pretty much be on par with a set of 572-13.

Save your money and move to the b1-MC's.

What is your power goal?

I run the 572-13 and not only like them but run fast with them.

It will cost you a lot more $$$ to change over to the B1 stuff over the 572-13.

"I run the 572-13 and not only like them but run fast with them."

MRMOPAR570 could you give a quick rundown on your combo and weight of your car and what it runs!

Thanks

Happy with ours but if I were to upgrade I'd go to the B1 PSO's. Also interested in the above combo.
Best machine has some good flow info which may help with your choice.

I am going to put a fogger on and spray about 300hp to 500hp the B1s or 572-13 the car has to make a lot of power but try and keep the cost down ? THANKS for all your help just would like to know what all you guys are running .

You really have to make a decision on what power you want the engine to make N/A.

If your goal is 900-1000 i would not touch the 572-13 and go right to the B1's or B1'MC's.

If you want 1000+ then start looking at the preds or PSO's. But at this point saving money is not easy

Thanks that is what i was thinking i guess i may try a set of B1s or 572-13 and see what happens. THANKS

I was going to build a 572 and changed my mind..I sold all the engine parts including the 572-13 heads..

I have some pictures you may want to see...they are of the heads ported...they were done by Hensley about 10 years ago..never flowed them but by the looks they should have flowed easily in the 400's..

I was looking to make 1,000hp..many guys in Nostalgia/SS are making in the 900-1,000hp range..

Steeldust,

Can you post some performance numbers for your car with the -1's on the 572? compression , weight, et , etc?
Mopar Rich in conjunction with Mopar Engines West are building me a 572, we will be using the 440-1's off of there 2006 Mopar Muscle engine challenge motor, (these same heads have gone 9.20's on my 500" pump gas motor, which was the original challenge motor) after reading this thread I am more convinced to stay with the -1's for now as I really don't want high rev's to make power. Our current motor with -1's that aren't quite as messaged is making just under 800hp and has ran a best of 9.04 at sea level in a 2825 pound car. The goal is to run in the high 8's on pump gas, we will also be losing some weight as the block will be an aluminum KB.

Great comparison, 10K for pso's versus 5K for 572's. Did you run both of these heads to form this opinion?

Re: WHOS RUNNING 572-13 INDY HEADS - 02/16/12 04:22 PM

Some more foood for thought. Don't get all caught up comparing flow numbers there are more differences that make horsepower between the 440-1's and the 572-13 heads.

Keep in mind due to the aluminum block you are going to give away some horsepower. (but i'll take the nose weight and ability to repair)

part of that 10k would most likely be Ti valves, and the porting. I would like to know where a guy can by a set of 572 heads, cnc ported, with Ti valves and the GOOD valve train for $5,000. I spent a lot more than that for my 440-1 set up. Had I been smart, I could have waited a couple of seasons and picked up 200 hp for about $3500. That would be cheap!

i agree, like port volume for one...

A good engine is a combination of parts not just flow numbers. Will a set of PSO's really pick up 200 horsepower over a set of 572's?

We'd be looking to go 8.50 / 8.60 at that weight with our motor. Some specs are in sig, heres a few more. Less than .750 net lift, shift @ 6500 and sees 6850 ish through the traps.

PS FWIW the KB was worth a 70lb saving over a Mega blocked 528 with the same heads.

Re: WHOS RUNNING 572-13 INDY HEADS - 02/17/12 03:45 AM

i did a pretty basic 572 a couple of years ago.
i went with the CNC365cc 572-13's so the peak power would happen at a lower rpm.
flat top pistons(14:1cr), World aluminum block, 440-3X intake, 1.7 rockers, .825 lift cam with very mild ramps to save the springs.

made 920hp on the engine dyno, 778hp at the wheels, and has gone 8.33 @ 165 at around 2750lbs.

keep in mind that the 572-13's and the 440-1's have the valves in different places and at different angles, so new pistons would be required to switch from one style head to the other.

i'm going to be doing the same basic motor as that previous 572, but will be using the 440-1 CNC345's this time around.
i am interested to see what the power difference will be.

I have not run it to see how fast it is i was running it in 6.0 class and i mist 4 races at start of points last year but when i did start running it was in the heat and it run 1/8 mile 5.94 et at 120 mph with 1.30 60ft and slowed it down a little with a 7531 msd and tuning but i may try to run in a real fast class that`s why i was asking about the 572-13 heads right now my car will go faster with tuning and good air here`s the car wt# 3,210 ladder bars Dana 60 456 gears 31x105w slicks 727 trans with brake 5,000 stall but leaving at 4,200 and shifting at 6,800 with alum block 13 to 1 comp steel rods 671-694 lift roller cam 1.6 T&D rockers and 440-1 out of the box no port work on alc with one 1050 Dom and take it easy on the motor down the track i think in good air and put the tune in it the car will run in the 5.70s or 5.80s around here this may not be to fast but for what it is it`s not to bad i guess

Re: WHOS RUNNING 572-13 INDY HEADS - 02/17/12 12:49 PM

Is that enough carb.(1050)for the cubic "?Just asking because when i was running that size carb. i had heating issues(leaning it out)

and sense went to a bigger carb. and solve that problem.I'll be watching this thread hoping to learn something.........Good luck with what ever to decide to do......

Re: WHOS RUNNING 572-13 INDY HEADS - 02/17/12 12:59 PM

I think your car does pretty good...Another suggestion here would to be having the -1s massaged by Dwayne..He knows his way around those heads and you may get a pretty decent gain in power after they are opened up! Good luck with whatever you decide!

the 572 I was going to build, was for my 63 Dodge...the intake was to be the Indy Tunnel with 2-1050 Dominators...I sold the Callies crank and the mega block...

you will need at least a 1250 carb and if you are to run a single, look into the 440-3X intake..I have that on my 499...a lot of guys that do run Nostalgia/SS use that rat roaster by Indy with a pair of 850's...and some are 15-1 compression...

Seeing as how my motor had 378 flow when dynoed,and the PSO is a dedicated race head with 460 cfm flow, I do not see why it couldn't. If I give myself a generous figure of 900 hp out of the 440-1s with 378 flow, and the PSO should be an all around better head for sure in areas other than total flow. 460 cfm in a PSO combo should generate 1100 hp if built well.
Now if you are gonna say I have no more than 850 hp based on performance, then the PSO would easily make 200 hp more at 1050 hp.

steeldust & 70 satelliteguy I sent you both a PM. I don't know much but thanks to a lot of help from the members on Moparts I get by. And I am always willing to share any info. or help I can to any of my fellow Mopar racers,make that what little I know.

The only thing I do know for sure right now is my work load has been killing me for the last few days.

THANKS to all you guys on MOPARTS . The carb GEORGE RUPERT knows ALC carbs he made the carb for my set up it works perfect the plugs looks find and it don`t get hot and to put heat in the motor i run a lean out and ALC in the oil just a little the car run pertect for 6.0 class with BRADS help a good friend but if i go to try and run the BOUNTY i will have to go fast real fast so that`s whay i need to know about some 572-13 heads . I sent you a message BILLY . THANKS

Impressive. Very close to B1-MC's and the B1's have a bigger inlet too.
I'm going to stick my neck on the line and say the -13's are comparable to the MC's
