I want to order a billet keyed hub for my motor, but don't know which style to go with. Thunder Racing has a different hub for 93-95 and 96-97. Since I'm running an eagle crank, which do I need for my blower motor?

 

I got a ati balancer that comes with a keyd hub. Works great for me. (383 running 12 pounds).

 

Call ASP, they have what you need. $90 I believe.
The thunder racing hubs are just stockers with keyways cut into them, and have been known to crack.
