Go to Scoggins Dickey.. And make sure you get the LS7 clutch, not the LS6. Get the LS7 clutch, it comes with an LS2 flywheel. I think the total price for that was around $460.. I also got either the master or slave cylinder -- can't remember which one.. for a very good price.. All together I think I paid around $500.
Very good clutch and was very inexpensive.. You can also get an aluminum flywheel for another like $150 or so, I didn't get it because I didn't have the money at the time.
Hope this helps
