I was told when I bought this truck that it had a rebuilt 327. Now that it is having some issues, I need to determine what it really is.
Casting numbers are. Block front passenger side-VO202WB
Block rear passenger side--V5202WB
Block rear driver side------3914838 or 3914638
Heads are both-----------3890462
From what I can find the WB indicates a 307 block. I can't find a reference for #3914838,but #3914638 is a 327. The heads #'s appear to be double hump 327's. The truck is a '68. Any ideas? Thanks for reading my rambling question.
