Any ideas?

Built an lt1 over the summer, and swapped it into my 85 iroc, i have not gotten it running yet still doing some wiring, but i bought a h/c/i combo off a member at ls1tech and was just wondering what kind of numbers you guys thought would be possible?

Ported and polished LT1 intake with fuel rails
Holley 52 mm throttle body
FMS 30 # fuel injectors

Lt1 heads featured 200 intake ports with a 61 cc. Heads include Ferrea 2.05 intake and 1.56 exhaust valves, comp cam springs , all new retainers ,locks, guideplates and 3/8 studs. 3 angle valve job.

Heads have been flowed :
290 cfm @ .650 intake
208 cfm @ .650 exhuast

Comp Pro Magnum 1:6 rocker arms , Futral Motorsports chromoly pushrods, Comp lifters

Cam motion custom ground camshafts
234/241@50 with a 113 Lsa ( Hydraulic Roller )
.577/.596 lift


also going to be running hooker super comp longtubes

My guess?

Somewhere around 400rwhp and a little more tq? Maybe 410 or so because that port job sounds real mean, and that cam will compliment nice.

With that kind of a setup, you might want to look into slightly larger injectors...

i did not think i would need bigger injectors until i went forced induction. but i guess i will find out once i get it running. thanks for the guess!
