3941128 Crankshaft Question?

I am looking to buy a used 1128 Forged Crank. Are these things date coded or do they all just have the part number? I understand they are still available new today. Are there any signs that I can see visually that might deter me from buying one? I know to look for scoring on the journels. Where am I most likely to find hairline cracks?

Do you mean 3941178 for 302 or 3841182 for 350?

I would have these cranks fluxed first or have the guy selling it , do it . Pay me now or later.

I apoligize, it is a part number 3941182. This is what I'm looking for. I've heard forged cranks tend to get hairline cracks with age. Does anyone know how prevalent this is?

Re: 3941128 Crankshaft Question?

they do. hairline cracks can and WILL get bigger. id suggest buying a new one. if not then get one from someone that knows how to look for cracks. such as a machine shop worker. i know from experience that them guys are willing to sell stuff they got lying around somewhere. and the parts are usually good.
