650 hp should be a piece of cake for a properly built 400+ inch engine......roller cam, long rods, lightweight reciprocating assembly. the tough part is keeping all those ponies inside of the block.....it gets kinda crowded in there for 650 ponies.....if you know what i mean...

plug those steam holes and install plugs (3/4") in big deck holes then drill them to match gasket holes. do this before decking the block. If aroller cam, tap and plug 8 drain holes(above cam).
