383 Crankshafts

[Sleepychallenger]

I have 3 383 cranks, 1 70, 1 71, and not sure what the other is. Is there even interest out there for these or would I be better off scrapping them.

How is life treating you !??
Ok here is my  the 383 cranks are similar to the 400 cranks but the 383 are steel cranks so they should be worth keeping , However anyone building 400s are typically using the 440 crank to get to 451 CI so demand will be low for them anyway .

Things are going pretty well. Getting ready to head overseas for a little while after the holidays.

I appreciate your $0.02. I'm not sure what to do with them since they are just sitting under a table in the garage taking up space. My 383 dropped a valve a while back and I decided to go the stroker route and have these extra parts laying around that I just dont know if I should hold on to them or get em gone and say oh well

The 71 383 crank could be cast. I think the forged ones have some value as well but only at a local swap meet.

The guy I picked up the 71 stuff from was telling me one was cast but dont know how to check. Got 2 cranks from him. Pretty much got an engine and a half from him and only needed the block

True the 383 2 bbl could be cast
if the counterweights are rounded & look stretched they are steel , if they are perfectly formed with sharp edges on the counterweights they are cast

forged is on the left

I'll have to dig them out and take a look.

Stand them up on the flywheel side and grab a medal wrench and give them a quick hit. The forged will sound loud and sharp ring and the cast will be more of a thud. OLD SCHOOL WAY !
