Absolutly !! I have been running one for years..My '56 ( pictured ) runs a consistant 12.5 @ 107 mph with a motor out of an old ski boat..Tha block is the same..Just make sure it was a fresh water cooled block..It ran antifreez thru the block..Raw water cooled engines were cooled by sea water.Mine was reverse rotation engine..But I used my stock crank and new pistons..cam etc.
