4.8+psi =???hp
Havent seen many 4.8 with psi setups?
build is .030 4.8 with 241 heads arp head bolts
6.0 mls head gaskets, mpt70 turbo, 00 camaro cam
3in. dp.
scr came in at 8.6 with 6.0 gaskets and 241 65cc heads
.010 out the bore.
turbo is t4 rated to 650hp
this isnt a race motor obviously, going in project s10.
fuel system is 42 svo inj., return fuel -8/-10 with aeromotive 1:1 fpr
and twin 255 walbro intank with stock efi tank.
any predictions of of hp???

I have a boosted 4.8 and I can't for the life of me think of a good reason to keep it a 4.8 and rebuild it for boost when it is so easy to swap in a 5.3 crank and some new pistons (since your boring anyway) and enjoy the increase in torque and cubes you will get. Same money (maybe more if you have to buy custom pistons)

that turbo is good for 600+rwhp and i think you could get there with that set up. have to run good fuel to push it that hard. probably run those 42's out. if you dont allready have them you might want to look into some 50's or 60's.
i dont know the specs on a 00 cam but i think a 01 or 02 z06 cam would be better for very little money.

from other builds.
wont see that much psi, unless at track
