Once heads are swapped for lower CR and boost is upped to 17 psi that will be really impressive cost and power wise.
Not trying to knock it down. Great job guys.

When you look at bone stock 5.7L dynoed at 540RWHP with 7 psi and look at the cost of this Head/Cam/Intake 402 ci with 635RWHP at 7 psi, that makes me think it's not cost effective.
I know some people might say they don't care about cost. Either way, those are impressive numbers from 7 psi only. Imagine what will happen with say 17 psi.

Maybe look at it as cost vs. power potential. 635rwhp is a great number for 7psi and the potential to run 15psi is always there now. That help rationalize it?

The numbers don't need to be defended. What I orginally set out to do was a 550rwhp street driven stroker, came plenty short of that, instead of tearing down my motor, going with bigger heads, swapping between a few camshafts, sheetmetal intakes and trying to make 19:1 compression, I left in a set of Diamond -15cc dish pistons, added the turbo system and have made more power then an NA 402 will ever have; considering a compression ratio under 14:1.
Still running 93 octane.

I am going to assume this was on pump gas?
Anymore pics available of that fuel system??

-6 feed line, Hobbs switch 2nd fuel pump, we have run this fuel system design up to 950rwhp.

Did you eat paint chips when you were a kid?
The diferences only become greater when the boost is raised as well, but I guess thats the part you don't get.

100 more RWHP, is it from the added cubes 402ci/Heads/cam/intake or claimed 7 psi.
Do yourself a favor and wait tell you read enough to respond.
