The machine shop has given me the following information.

Keith Black Pistons (Flat Top) .030 overForgot to ask compression ration, but pump gas friendly.

4.250 Crank (Total Displacement 489)

454 2-bolt block. 049 heads, Ported, Polished, Bowl Blend, and Increased valve size.

the suggested cam:

234/244 0553/.578 112LSA

Performer RPM Intake.

Melling High Volume Pump, Clevit Bearings.

Proform 1.7 Aluminum Roller Rockers.

Would you suggest a different cam. I have power brakes and want to maintain their use. What kind of power are we looking at, Guesstimates?

Thank You,

Big D

what's the cc of the heads now? did whoever did the head work cc the chambers?

Otherwise, the worst thing I see wrong is the old Melling HV/HP oil pump. this is not needed.
