Re: 1971 ls6 double disk clutch
Others know more details, but I believe this clutch was available (or part of the engine option package) with other solid lifter big blocks. Years ago, I had a '70 Chevelle SS L78/375hp with this clutch.
I believe it's discontinued long ago by GM.Mark Edmondson

Stock for your LS6, as Mike said. It was an option with some Corvette engines in 1969 (maybe 1968 also, but I am unsure of that), but not a Corvette option in 1970-1972.Terry- Top

I have no information that any Chevelle ever was originally equipped with a dual disc clutch. I once was the original owner of a 1968 Chevelle SS 396 with L-78 and M-22. It did not have a dual disc clutch and I do not think that any 1969 or 1970 did, either.In Appreciation of John Hinckley- Top

The dual disc clutch was used for only 2 Corvette applications ever. The first was 1969 Corvettes with L-71 engine and MA-6 dual disc clutch option. The second was all 1971 Corvettes with LS-6 and 4 speed transmission.In Appreciation of John Hinckley- Top

1969 with MA-6 used 10 spline discs. 1971 with LS-6 used 26 spline discs. Otherwise, the clutches were the same.
Also, I believe that all 1971 with LS-6 and 4 speed transmission, both M-21 and M-22, were equipped with the dual disc clutch.In Appreciation of John Hinckley- Top

If you ever need any components of this clutch system you will probably need to convert to a standard single disc clutch. All of the GM parts for this clutch system are long-since GM discontinued and I know of no reproductions or aftermarket replacements for any of the components. Given that the market for these parts is infinitesimal, I highly doubt there will ever be available such parts.
Once-in-awhile one or more of the components comes up for sale on eBay at withering prices.In Appreciation of John Hinckley- Top

I digress. When purchased, the power brake pedal had a custom fitted block mounted on top so its height closely matched the clutch pedal. Oh, the prior owner was about 5' 5" tall and had issues walking. I assumed the clutch was original, but maybe it was installed to reduce effort or travel?
Still, I'm surprised you don't think any non-Corvettes came with this clutch.Mark Edmondson

Possibility that these folks can rebuild the dual disk clutch http://carolinaclutchandbrake.com/ I don't know of anything that has stumped them yet.Dick Whittington- Top

I have no information that any other Chevrolet model was ever originally equipped with a dual disc clutch. This includes 1970 with LS-6. The car of which you speak could have been retrofitted with one or it could have been retrofitted with some sort of aftermarket dual disc or other clutch.In Appreciation of John Hinckley- Top
