I have a sbc that I can't find any info on. The casting number is 3 14636. Yes there is a space between the 3 and 1. Any info would be greatly appreciated. I have not taken it apart and would really like to know if it's a 2 or 4 bolt main. Thanks!! Posted using the Full Custom H.A.M.B. App!
Welcome from Chicago! I think there should be a 9 between that 3 and 1, 3914636 which would make it a 1968 307, 200 hp, 2 bolt main.
