Hey Dave,
I'm still on the fence about just buying a crate motor or spending the money to re build what I have. I'm still trying to actually figure out if it's truly a 390. I don not know the history of the car. I know the VIN number says it originally was built with a 390(2V reg. fuel). The heads are C8AE-H. I cannot find a number on the block though. The block has a few marks but I have not been able to find any number sequences yet. I think I'll have to get it completely out maybe. There is an "X" on top in the oil Valley- it's about 2 inches in size, and also a 44 just above it. The front has a 352 with a 54 not far from that. Just below the oil filter there is a -W- with to screws embossed on each side of it. and there is also a V next to that. I also found a DIFF mark as well. Any help would be much appreciated.
