Well I got taken but good. I bought a 1967 Corvette that was suppose to have a 427. Casting number 3904341. Everything that I have read or have seen says that's a casting number for a 1967 427, 2 or 4 bolt. Well I pulled it out to build it back to specs and long behold its a 396. Anyone else run into this? Does the mighty scrolls need to be updated?
