I need to buy a new crank hub for my 383.
Its keyed, and it needs to fit the stock damper design.

I was looking at the ATI keyed hubs, as they are not too expensive, and they have light weight aluminum ones.

Does anybody know which one will fit?

I ordered one from summit taht I thought would fit, but its got too large of a diameter where the hub fits over, so my hub wont fit.

please help!!

thanks

Sounds like you need a keyed stock damper. Try Thunder Racing.... they may sell one. Or you can have your stock hub keyed. If you are building a high performance engine, why not upgrade to an SFI-rated damper, like the ATI?

 

I did get a new damper, but it matches the old stock damper in the way it attaches.

is it worth it to get a key aluminum hub over the heavy stock one?

 

When the weight is that close to the center of the crank, is makes very little difference.
