Napa - Gates 650 is what was on there with the 3.1, when it was slipping. I have a 660 gatorback on there now with the 3.25 pulley.

I ordered a 3.5 tensioner pulley and a 660 Napa Gates belt today though. I'm about done messing with this though.

I did run with a 01 Vette yesterday and stayed with him, which made feel pretty good. The Vette is a 5.7 auto, that a good friend of mine (member here) was driving. Other than that, I'm getting a little tired of this car...I'll get over it though.
