Engine Identification

[Owen G.]

Trying to solve a riddle. The engine in my 1965 Corvette is a #3782870 with a casting date of 4/3/65. The build date for the car is 6/8/65. The intake, carb, exhaust manifolds and heads are correctly numbered. My checking says the engine is a 327/350hp. The engine pad has no numbers stamped on it. My thinking is that the engine pad numbers were machined off sometime in the past or that this is a replacement block. How can I tell one way or the other?

There are no broach marks at all. The pad is smooth.

Re: Engine Identification

If the block was "decked" in the field the pad will likely have circular tool marks, but any/all paint must be removed, and it may take strong light and magnification to see them.

Owen, I think you have a 65 motor, but to early for the car to be the original, even if it is decked. A June 8 car normally would have a motor dated May 15, or close. NCRS accepts 6 months, and you have that.

Just drive it and enjoy !!
