hey ive got a 350 2 bolt, 3970010 block, its bare, had a rod knock so i pulled it, unless your gonna throw some mayjor nos or alot of blower pressure at it, the 2 to 4 bolt shouldnt matter, plus if u get splayed caps and get a 2 made into a 4 bolt, its stronger because the stress is put on the sides of the block instead of all the middle, im loacated in mid michigan, willing to sell for dirt cheap
