you didn't mention the exhaust or headers that are going to be used? good, free flowing exhaust can help a bunch, the tubes wouldn't have to be huge to offer some potential..

HP ?? guess
I had Joe Ryne do a rebuild very similar to this, awhile ago Mine had approx 10.25 to 1 compression yours might be a little bit
lower but probably close 9 to 1 depending on the dish and CC size of the chamber. (total combustion chamber volume)
anyway with a 750 holley DP it made 402 HP on an engine dyno and similar torque numbers. So it should be in that range probably 375 ish HP.
Mine was a street pump gas motor Sounded great and had good power.
