383 piston choice

The engine combo that I am collecting parts for is:

KB400 pistons
Mopar .528 solid cam
Stealth Heads
RPM intake
750 Holley
Mopar ignition w/MSD box
I think that the compression is said to be 10 at 85cc.

I plan on this being my daily driver in my 63 Dart with a 4 speed, 3.23 8 3/4, Hi Po manifolds, 2 1/2 exhaust on pump gas.

Thoughts, comments?

Thanks,
Mike
