Talk to me about clutches

[VintageMusclecar]

About to pull the trigger on a clutch kit for the Chevelle, considering the RAM musclecar series or powergrip clutch. I'm trying to stay away from the "box-buster" killer clutches like the Centerforces, etc., since I'd like to try to keep my Muncie intact for a while. I don't want anything that hits hard (i.e. on-off switch syndrome), and the street tires will be the fusible link in the system.

(Seriously considering a slipper clutch later on for some additonal track tuneability, but for now a street [/strip] gig will have to suffice.)

Whatever gets bolted to the flywheel will need to hold 600 real-world HP. (yes, I've got a few tricks up my sleeve waiting in the wings for the 496...but that's another subject)

Thoughts?...advice?...experiences?

Any help/input would be appreciated.

Thanks
Eric
