Thanks for the heads up. Although I do get a GM employee discount, it wouldn't lower the price drastically less.
For that price I'd buy these... South Florida Pulley Headquarters - Your source for supercharged performance products! . These have been proven to be very well built and durable. Infact, Zooomer ran several 10 sec passes on these without failure. Anything Terry makes at SFPHQ is high quailty, great man to do business with. For $475 plus shipping, I think the realibilty stand point maybe worth it. Not sure if I'll save for these though. I'm not a frequent drag racer anyway, although these shafts would potentially out last my car...
