I say stick a boost friendly cam in that thing, some 120lbs injectors, upgrade the fuel system, hit it with some E85, 14lbs of boost and let it eat!

haha not going that crazy yet, i have a pretty good fuel system already 340lph pump with a procharger boost pump. i was thinking 65lb injectors or 83lb injectors. the cam will be the next thing on list after the procharger is done. i want to stick with 91 pump gas not e85.

Re: lsx376 procharger

i am running a pro built pro street elite 700r4 handles like 800hp with a 3200 9.5 stall. everything is pretty beefed up even the stock 10 bolt has moser axles aluminum girdle and a few other things done to it. i dont drag race so it should be ok for the time being.

Re: lsx376 procharger

Wow..sounds like it's gonna be a beast! Good luck with your build.

That 10 bolt will be very short lived getting smacked around with all that torque. I'm only putting down 440 to the tire and I'm glad I invested in a 9 inch a couple years ago.
