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.
What he said!

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.
