Add this to my last response...

Also a couple other things to consider.. how is your cooling system? The larger 671 supercharger is takes mpre energy to spin so you will likely notice your engine temp will be warmer vs the smaller supercharger.

Also depending on the power you plan to run it might be smart to have a second key cut into your crank.

I am happy to answer any questions you may have also.
