1966 C2 Engine Codes

[Gregory H.]

I have a 1966 C2 Corvette with a 327/300hp motor date Code of CE8 63793. Can someone advise what the CE stands for? Counter Exchange motor? Also, the motor's casting number is K 30 7, which I think means Nov 30, 1967? Thank you. GH

CE was used for replacement engines from Chevrolet. I would guess the engine was replaced by Chevrolet under warranty

Thanks Bob...this does help. I was told that the motor was replaced by GM in early 1967. Greg

Yes, ''CE'' is the service replacement. Casting date K 30 7, is as you say November 30, 1967. So it was probably replaced at the dealership in the winter of 1967-68.

I think CE8= 1968 replacement, sequence # 63793, which if we had the work order from the dealership would confirm when and what dealer received the short block. Chances are your original heads and intake and carb and accessories were re-installed. Are you sure your car was a 300hp at birth? What is the tach redline?

I believe that the letters "CE" = Chevrolet engine. As other have stated it is a service block.

Is the casting number "3892657" or "3914678"?
