You could go to summit racing and get a better clutch. This is a Hays. EB recommended them when I talked to him, said that they were one of the best...He may chime in and clarify that...I don't want to put words in his mouth. I have this one and don't have any problems and it's held up. I wouldn't trust a clutch from autozone myself.
Hays 90-400

Looks like they are running some kind of special on it. $30 bucks back to spend at summit if you buy it. Could come in handy for some MSD wires. Good Luck...
