Default Patriot Stage 2 5.3l heads and 231/237 heads/cam swap soon

Doing this soon maybe anyone can chime in on what gains they have experienced, i am hoping for 400 whp, i put down 337.

They are patriot stage 2 5.3L heads with a comp cams 231/237.

i am doing upgraded oil pump, double roller timing chain, and pushrods, the heads come with .650 lift patriot springs.

all i need is the gasket kits and install with a tune and im flying hopefully!

any opinions, questions, or comments let me know im excited myself

Mine have served me well since 2003 with no problems. Do your homework and optimize SCR, DCR and quench. Building a good motor is all about combo matching.

i made 420rwhp and 385 rwtq with that combo and did 445rwhp on a dynojet. I did that on a ls6 intake and t/b and just added a fast 90/90. I cant wait to get it retuned. I might just throw in the ms4 for fun. Did u already buy the cam, if not mine will be for sale shortly??
