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

The Pump just comes as part of the kit, Don't know what the CC will be, the heads haven't been reworked yet.

I read alot about the VooDoo 268 cam.... should I go with this?

If you take the 049 heads, put larger valves and some mild porting, with the combo I described above what kind of power would I be looking at.

I'll verify which pump is gonna be in the motor and go from there.

I would still like if someone with a Desktop Dyno to run some estimates to let me know what kind of power I can expect.

Also, anyone have anything to say about the Cam?
