Re: 71 442 W30 - Two Plate Clutch? Interesting...
The Olds guys should know better. Check out some old road tests or 1971 intro features and you'll find it there.

------Having had a couple of dual-disc clutch Corvettes and driven others as well, I can tell you that they are pretty much bullet-proof. Oh yes,,,, I have abused them. Easy pedal too. I have always thought they were just about the perfect clutch, at least for me, anyway!...........Bill S

Re: 71 442 W30 - Two Plate Clutch? Interesting...
I'm thinking that dual disc option was only available on Olds in 1970 and 1971. Lots of clutch warranty back then. The 1968 W31's used a 11 inch Scheiffer unit (with a GM part number assigned)that took a leg like a Sumo wrestler to drive in traffic. I think the only other GM production application for that clutch was the big 427 Vette (L88?) around then (1968). Needed it for the high RPM uses. It was not used on the W30's or any other Olds back then. Not sure if 1969 and 1970 W31's also used that Scheiffer unit. Don't think the dual disc option was ever used on the W31.
The dual disc was a sweet one to drive as the pedal pressure was low like a standard clutch, but would hold up. Remember seeing cars built with it, but have no facts or figures.

You guys talking about this? http://cgi.ebay.com/ebaymotors/ws/eB...category=34208 [/ QUOTE ] Yes. And this one. http://cgi.ebay.com/ebaymotors/ws/eBayIS...ssPageName=WDVW I think the used one was a bargain. Any good clutch shop could rebuild the discs. Lynn

Looking forward to seeing some pictures of your car, Colin.
Do you happpen to know anything about the '66 Shelby that had to be cut up as a result of the serious accident at Road America last month? I heard the driver is doing better.

Re: 71 442 W30 - Two Plate Clutch? Interesting...
You're probably right, Diego. Did it carryover to 1972? Everybody had given up on the performance side about that time and was concentrating on emissions. We all kinda lost interest at that point.
