440 crank in 383 block

There was never any nitriding on 440 cranks. 426 Hemi, and IIRC 426 Max Wedges. None on factory cranks. Nitiriding is only about .030 deep at best, so he's right about cutting past it... But the crank has to have been hardened first. Mopar never did it that I'm aware of. There's a lot more I don't know than what I do...lol Can anyone find something beyond Brandon that says that? I'll check my books tonight to make sure. Brandon's cranks need to be inspected carefully, but the cranks are better than the rods. I have yet to have a set of them that didnt need to be re-sized properly to be right. Definately watch the bearings too. You will have to chamfer them.
