My current set up feels slow. 5.3 @16psi
Basic rundown, 60lbs injectors, meth, ring gap opened up, gaskets and studs, 75/76 turbo, 5 in IC, rebuild heads, springs, pushrods stock bottom end, new bearings Triple 12 Isky Cam 212/212 112 .561
Dynos 630/630 whp/tq

I'm shooting for 800whp.
I was going to do 102m intake and TB
trick flow gen x 215 heads
walbro 450
120lbs injecotrs and fuel rails

I'm very unsure of piston and rod selection, Mostly Pistons. I am unsure how to match my pistons to my heads combustion.

 

 

Sorry about that edited my OP.
5.3 @ 16 psi 93 / meth

 

After using my eyeballs to read, I don't think I can run the heads on and stock bore 5.3. Says they require 3.900 min bore. Guess I'll kill this 60e with a 6.0
