Whe I first got my K5 it had the original 3finger pressure plate in it. Felt like a clutch on an old tractor hahaha
I then installed a Centerforce 2 cluth kit:

Some say CForce is more for mucle cars and that the cintrifical weights fall off, but I never had an issue so?
Wheeled this clutch until I pulled the 350 out. Never had any issues, I did "smell" it from time to time and when I pulled it I could see some heat color. But with all that friction I would expect some heat.
When I shoehorned my 454 in I got a 30lb Hays Flywheel and 12" (11 7/8") LuK Pro Gold cluch kit:

I have about 4yrs on that now and so far zero issues and I have hit drags out on the dunes as hard as I could trying to beat my buddys truck(can't really shift a 465 that fast but I tried hehe)
