Should be a 4 bolt main also
engine information
I am going to buy an motor hopefully this weekend. If I could get some help on the numbers it would be appreciated. Start Heads 3973487 A41 GM7 other head 3973487 A31 GM22.
Block information (I hope these make sense) 3970010 A211 GM V0123TBC(I origionally thought the suffix was IBC but I did not see that code) 12 242 2 010 H31not sure of the 1.
I was told block and heads from same engine late model truck. I did check and think heads from 71-72 350 LT1. I would like to know if these all were from the same engine and is the block a 350. Let me know if I need to check any other numbers. thanks mike
