Was wondering what I would get if I put a 1983 305 HO Crank & Heads to a 1979 350 Block

Anyone do this yet or can steer (No pun) me in the right direction

The 350 Block was stripped to the core and given to me for free...

The 305 HO was stock and almost complete (Minus the carb & distributor) and also given to me for free...

The direction I take with one of the blocks bored .030 Over and rebuilt
