Thanks, I'm about 99% sure it's an "I" not a "1", You can still read them clear as day. The back of the motor is very close to the firewall, so I can't tell those numbers right now. It dosn't matter what motor it is until I pull it anyway, because that is when I'll decide what to do with it. I know it may have some value, especially if it's the vette motor it's supposed to be. It's got adapters for the motor mounts to the stock frame mounts, they go straight into the sides of the block close to the front. Looks like a fuel pump block off on the passanger side, got an electric pump on the frame. I doubt the engine's ever been apart, will the numbers on the intake tell me anything?
