Alright guys, any estimate(s) would be greatly appreciated; I'm probably sticking to 93 octane but I've not ruled out E85. If anyone has a guess for the E85 though, that too would be appreciated.

LS2, stock dimensions, stock internals, no spray, no boost
PRC Stage 2.5 LS6 heads
PRC .675" Lift EHT Dual Valve Spring Kit
2.02"/1.575" Stainless Steel Valves
TSP Torquer V3 cam, 231*/234* duration, .644"/.598" lift. 111 LSA (should be > 316cfm intake and ~226cfm exhaust)
FAST LSXr 102mm intake
102mm TB
ID 725cc injectors
4" intake
1 7/8" longtube headers, 3" exhaust

Thanks in advance!

Auto or stick?

My fault. Right now I only have a T56 but in the future I'll be upgrading to either a TR6060 or TKO600.

Depends on the dyno, but on 93 octane 440-450 might be possible on a good dynojet dyno

Thanks. I also suspected that much; previous owner claimed it made 510ish to the wheels if I recall correctly. I thought I smelled BS though.

I have pretty much an identical setup on a 346 and made 435hp 404tq. So Im assuming with your more cubes and better headers you should put down another 20-30! Keep us posted tho!

I'm still playing with a lot of custom wiring and switches so it probably won't be for at least six months or so, living in the north and graduating from grad school... Thanks for the help though.

You're right the 510ish whp is BS. I guess you're right in the 440ish whp range on a good dynojet. Curious what makes you believe the heads flow greater than TSP's advertised 316cfm on the intake?

Higher cam lift even though I know it may not flow more...
