Called comp cam and they said with these heads
# SB-Chevy S/R Torquer Cast Iron Cylinder Head170cc Intake Ports
# 67cc Combustion Chambers
# 2.020'' Int/1.600'' Exh Valves
# 1.250'' Valve Springs, .560'' Max Lift for Hydraulic Cam

that this cam would be prefect for what i'm looking for.
# "XFI" 252 Hydraulic Roller CamshaftChevy 262-400ci 1955-98
Lift: .550"/.546" w/1.6 Rockers

RPM Range: 1000-5000
Lobe seperation: 113*
Good for 305 or 350 TBI. Excellent off idle performance. Xtreme torque.
What kind of numbers do you think that combo would put out sitting below the stock TPI intake 355 block?

Re: Decent TPI combo?
I'm not sure on the HP. You might want to investigate what compression ratio you will wind up with the 67cc combustion chambers. Otherwise sounds good to me.
