I need to know who makes a full crankshaft key for the LT1. The minute you mention an LT1 they give you the stock notched key for it. I am using an aftermarket hub that requires a full key, future plans with the car will be the use of a supercharger so a need for this hub is required. Any ideas would be great, thanks

 

Have them match a notched one up with one that is not notched to get the size.

 

Would it be different from a standard SBC key?
