Too late, I took the valve covers off and then saw where the two numbers were. Obscurred by paint and some rust, they are number 16 heads. And yes, I also screwed up the block casting number which should have read 9790071. I am 61 you know and run a prison having worked there for over 37 years so my mind is a little mushy. The good news is that the intake is correct 9790140, the Quadra Jet is correct 7028263, the heads are correct, the vin is on the block as well as the WT and I believe the exhaust manifolds are correct but need to remove them to get a good look at the numbers. The transmission has a casting number of 3925660 which is correct for a 68-70 Muncie Transmission but I am not sure where to look for the vin. Also wondering about the distributor but don't know where to look for that number either. Any help with these would be appreciated? Thanks.
