Gents,

I would like to get a power estimate for my LT1 350 engine rebuild. Rebuilding it to a bit more than stock.

350 - bored .030 over, stock bottom end
Fuel injected
Approx 10:1 compression
Stock intake - port matched plenum
Stock heads - ported exhaust, bowl cleanup under both valves, stock valves (1.94" in/1.5" ex)
1.6 roller rockers
Headers
6-speed
Comp Cams hyd roller (268XFI HR13)
Operating Range: 1,800-5,800 RPM
Advertised Duration: Intake 268° / Exhaust 276°
Duration @ .050: Intake 218° / Exhaust 224°
Lift with 1.6 Rockers: Intake .570 in / Exhaust .565 in
LSA: 113

Any ideas on power output?
How much vacuum will I get?
Will this cam have a lope?

I'd like to keep this engine street-able with a good idle. It will be running daily driver duties with the wife driving it from time to time. There is also an option at the machine shop to put in larger valves (2.00" int/1.55" exh). Not sure if it is worth it or not. Opinions?

Thanks,
E.

Anyone with Desktop Dyno care to comment?

Im planning on doing something very similar and was also wondering the same thing...
