Just found out the crank was not a 3.58, it was a 4.0 so instead of a 359 it is now going to be a 402CI Monster! Can we say 500hp with these heads??

I think it will come down to the correct cam choice as to how close it will get!

We made 485HP with our little 410 using that comp 295HL hyd. cam and same heads. Open the pushrod pinch up, and use a Holley 950HP and it should make 500HP. With an rpm intake as well!!
