35035069c3

Hello Members and Experts,
I'm having my numbers matching 1969 L46 engine rebuilt. I know the crankshaft is forged due to the wide casting rib, however there is no casting number or stamp, just GM and (maybe an H - unrecognizable - sorry no pics at the moment) - Is this common, or do I have a problem? The block and engine type is correct for that period - 3932386. The car fits the early 69's in most of the facts I've read.

Thanks in advance

It should have a number on one of the rough finished throws or counterweights towards the front of the crank. Do those areas look like someone has been in the engine before you and polished them?

The engine builder said he'd never seen one without numbers, he could also tell it had never been rebuilt.. it had the original compression head gaskets and the piston caps had the so called crack sound when removed. I know the previous (original) owner, and he said the only thing ever replaced was the camshaft, which happened to be done by my brother (Chevy Master Mechanic). It's very odd to me, so I thought I'd toss it out on the forum.

Chevy cranks have numbers. If yours actually does not show numbers, the numbers were either removed or it is not a chevy crank.

Once I get the long block back, I'll take a closer look. So far I've just been told it has casting identification "GM" and some unrecognizable character. Thanks everyone for your input - the aftermarket China crankshaft comment made me laugh.

Looks like 1182 to me. Same one I have in my 69 L46.Nice factory forged crank.

That picture is what it is supposed to look like. We just need to see the OP's crank.
