Finding engine numbers info

Like I said in post #9 find the numbers on the front of the block and that will tell you when the block was put together. I have a 70 block cast on 7-1-70
but had a problem and wasn't built till May 6 71 almost a year later and was almost a 1972. The casting date really doesn't mean much but the date it was cast.
