Centerforce is an excellent clutch for you, stay away from findanza, there is no support from them if things go bad. Talking from past experiences
"Speedy427", Could you elaborate a bit on your comments about Centerforce and Fidanza products?
What makes a Centerforce an "excellent" clutch? As for Fidanza, you've made some pretty damning claims, however, you've offered nothing to back up your seeming slander. How about posting some evidence--some specifics--to support your statement about "no support".
Also, rather than hiding behind a screen name, why not add just a tiny bit of credibility to what you say, by putting your name on it?
The name Luk keeps coming up in this thread, but it's unlikely Luk has an aftermarket clutch application for a car that old. Luk has only been a clutch supplier to GM since the late 80s. The person who made the original post is talking about a late-60s/early-70s style clutch which was used into the last of the C3 model years.
A good clutch for a car using an other style lever-type or diaphragm clutch is made by McLeod Industries. They have applications for Vettes going back into the late 50s as well as replacement clutches for the newest of C6es. I've used McLeod clutch parts in all of my older vehicles...my 65 Malibu, 71 BB Coupe and my 95 C4. I also have McLeod pieces in my 01 Camaro. The quality has already been good and the support is reasonably good, too.
As for "how much" clutch you need...well that depends on 1) what you do with the car and 2) how much torque the engine is putting out. For example, if you drag race a lot and you've got an engine making 500 lbs/ft torque then you ad a 200 shot of nitrous, you're going to need a pretty stout clutch maybe even a two-plate clutch if you want reasonable pedal effort. On the other hand if your engine makes 350 lbs/ft and your pretty much just a street driver, you really don't need much clutch at all--you can probably get away with a single place clutch having pedal effort not much higher than stock.
