Best 350 OEM Block

Carl… We've found the "386" and "388" blocks to be good also. They are usually Early 1968-69 castings, prior to the "010". The early 1969-70 "010" are very solid also, and in most cases have a "K12" behind the passenger cylinder head at rear of block. Always consider core shift that is noticeable at cam tunnel, try and find a block that has the cam tunnel bored centred with the thrust flange. Good Luck…MB.
