Jude, thats funny that you asked???? The number on Jim's block was 19N615034 with a casting of A9... This would have worked for you but it works better for Jim..

When the car came to St. Louis it came with its original motor. Sometime later it was replaced for some reason and the motor was separated from the car. Now 35 years later we heard of a 4 bolt main 512 block for sale and found out it was an early casting and my friend Mark Smith called me up and told me to go look at it and see what the VIN was. I did one better and called Jim and told him to meet me at my house and we would go and see the motor before the guy got wind that this could be Jim's old motor. So when we arrived at the sellers house we looked at the block and the two struck a deal. Jim and I both looked at the partial VIN on the block but we couldn't get past the "61" due to the repaint. I also think we were looking the wrong way considering the block read "19N61" but if you turn it upside down it reads the same. So we were looking the wrong way I guess, and also this was the same way on Saturday when Jim showed me the VIN again. We looked at the thing for about 5 min. before the VIN popped out at us very faintly. It was a great feeling to help Jim get this piece before it went into someone elses hands. Great story with a happy ending.
