I'd like to buy a twin disk clutch. It's for my project 1970. So far I have a 454 cubic engine (block bore and crank stroke). I plan to take it out to 502 cubic inches. (or 496 or whatever the sleeves can be bored out to).
I'm looking at a McLeod 6911-07 RST twin disk clutch. It's rated for a 800 hp engine. I don't think I'll build the engine up to 800 hp, so it appears the 6911-07 should be fine. For ~$200 more, you can buy the same clutch rated for 1000 hp. (A RXT clutch). The RST has an organic based clutch disk material and the RXT has a ceramic based material. For the $200 more, I would otherwise just buy the RXT version, except that the ceramic based disks are described as having a "slightly" aggressive bite at clutch engagement. I've already experienced the problems a trying to buy the "best performance equipment" and driving them on the street. I'm not going to be seriously drag racing this car. I would like a livable clutch engagement, but of course I'd like to know that the clutch could take any future hp upgrades. Anyone has some comments or experiences with these two clutch products. Also, if someone has a recommedation other than the McLeod clutches I be interested to read.

About the "best performance equipment" comment. I bought one of the "best" suspension suspension upgrades from VBP for my 68 Convertible. #550 pound coil springs and a 460 pound rear monospring. With a lot of aluminum upgrades and also deletions, the car probably weighs below 2900 lbs. The suspension is so stiff, it's really not the optimum for highway driving an terrible for city streets. I want to build my 70 as a high performance car, but don't want to add things that make it ackward to drive.
