Rebuild 383 bottom end...

Well, measured the 915 heads to a tiny little less than 8cl which should be about 80 CC, zero decked block and MrGasket 040 head gaskets.
Eddie 600cfm carb, dual plane Mopar M1 alu intake, HP manifolds with dual 2.5" exhaust.
What HP do you think I can expect with the CR and cam shaft above?
