Hey guys. I just want to get some input on an engine i built recently in my 76 Firebird. What kinda numbers should this make??

Pontiac 350:
-Bored .040 over
-Wiseco Flat tops (8.5:1)
-Power seal rings
-Mellings Cam (204/214 dur. .422/.444 lift)
-BB chevy adjustable valvetrain
-6X-4 Heads shaved .030
-Stock Intake Manifold from 1975 455
-Holley 650cfm Spreadbore
-ARP bolts

Just curious how much HP this set up is netting me, I'm Looking to add a Performer intake, and Headers.
Also a stall converter (th-350) and gears (3.42's)

Edelbrock built up a later 400 with 8:1 compression and used the Performer intake and cam (same cam specs as yours) and got 300 HP using small-tube headers. I would say close to 270 HP for your 350 with headers and the Performer intake, should make a nice street engine. The 3.42 gears are a must for good street performance, a 2500 stall converter will add quite a bit to this combo as well. http://forums.performanceyears.com/g.../icon_wink.gif
