TK 14 SS

I'm looking at getting the set (98-02 LS1 ASP948584 CRANK & ALTERNATOR PULLEY SET) and my question is... Is the alternator pulley overdrive or underdrive???

Boy, I just never stop learning this stuff

Thanks

IIRC its overdrive to keep the stock charging charactersitics the same

I am running the alt underdrive too and have no issues with the car. It gets close to the hash marks with extended idling, but comes right back up. Depends if you want max HP and if you are going to run any after market electronics.
