Hey Glenn and thanks for the reply. The 10A is the number that ends with the car vin number if I have researched properly lol. i took a picture but could not see clearly the last 6 digits. it looks like 10A106590. My plan when I got this was to put it in my 76 Corvette but after talking to others the amount of money and changes I would have to do I am thinking differently now. It is in great shape and was kept wrapped in a building for the last 30 years. It has cast iron heads that are marked 3964291 heads, 7115 forged crank that looks like it has been balanced and a double roller timing chain. The bottom half is complete so I have block, heads, pistons and so on. I think I might just sell it and purchase a crate 350 for my Corvette. I had it magged and it is good. Any ideas on what I could ask for it.
