Hi I would like to tell you about Bully clutches. I got my installed by Racetech. is a Stage 1 rated to handle up to 350hp. ($700Can) my engine is 350/300, stage 2 is 350hp plus and stage 3 is something that only DKOV would use on his baby. most street ricers use it and all said it's way better than Centerforce and last lot longer. they are custom made for your needs and application. oh www.bullyclutch.com
