Hello People I have a block that I cannot understand what it is. Any help you could give me would really help.
Block ID #CE952049 CE is chevy engine warranty or over the counter engine
Crank ID #8904815NF
Cylinder head ID #3981063
Intake manifold ID #3931067=396 / 350 69 Nova, Chevelle, Camaro Cast Iron, Oval Port, Hi-Rise, Q-jet carb
So everything points to a 1969 396 but the bore in the cyclinder is 4.25 not 4.0 or 4.1 so I am super confused why would someone use a 427 block with a 396 crank? I have not pulled out the rods yet so I do not know the length yet. The motor is frozen.
Thank you in solving this mystery

The block ID number you listed does not appear to be a casting number, but a engine/vehicle ID. Have you checked mortec.com?

BTW, 427 = 4.250" bore x 3.76" stroke. Hopefully that crank has been balanced for the 427.

can't find a listing for you head casting number, please double check it. also the casting number off the top of the rear of the engine might help to identify it better

3904815NF is the cast crank id number, not the block casting number

Because a 396 crank (3.76" stroke) is the same as a 427 crank (3.76" stroke) and the factory wouldn't necessarily cast two different crank blanks, but just machine them differently for balancing the heavier 4¼" pistons of the 427.
Go to mortec.com and try to find a specific "1969 427 crank" casting number.

Did Mr. Veneno ever figure out what engine he's got?

I'm thinking that Post #7 got him straightened out.
