The advantage of the twin disc, is great TQ holding capacity, and a LIGHT clutch pedal!
Very important in a street car.
Many here have used the McLeod twin disc and love it. SO it works on Corvettes. Some haveeven measured it.
Just make sure you get 10 spline discs, that's all.
Otherwise it's just a 11" dia. chevy clutch..

I’ll call them tomorrow because I have to get the 168 flywheel as well.
I appreciate you guys, Thanks!

The 6911-04 is a RST Street Twin for a Muncie 1-1/8" dia. spline, with 10 splines.
And you use your existing 11" flywheel.
I would call them as to why their on-line selector says it does not fit.
They must have one that does, or can tell you how to address that.
Do not be afraid to use a lighter than stock flywheel with a BBC.
You have plenty of TQ, and you honestly do not want to shock the diff too hard.

The problem is, in light traffic, you only need to nudge the car ahead each time. The nudging heats up the floater as the clutch is never fully released in stop and go traffic. The floated after a short time will warp and cause the clutch not to fully disengage.
The Tilton "floater" is MUCH thicker and does not get over heated in the stop & go traffic.
The McLeod is a good clutch, however, (in my opinion) it's not suited for light city driving. The clutch needs to be "in or out", not "slipped" in traffic usage.

My friend tried the McLeod twin disc, not sure what model, he found it worked great, however, in stop & go traffic, the "floater" engages first, as you release the clutch, then with the clutch fully released the "sandwich" is fully engaged.

FWIW - my '68 with M21 3.08 rear and 489 with 570 hp/606 ft/lb tq still has, some 12 years later its Center Force Dual Friction clutch (and steel flywheel) - never any issue with slippage - pedal is perhaps a little lighter than stock or other alternative aftermarket clutches. Initial 'burning'/breaking-in the clutch-in on a fresh engine was a little challenging.

I have been fortunate enough to have driven over a dozen dual disc clutches. From several mfgrs, including GM.
On all of them, you can feel that the "engagement" point is a little different, a little bit wider, vs a single disc.
Even on an all-brand-new-clutch & flywheel GM system.
Sometimes you can feel one disc hit, then the 2nd.
Other times it's just a little wide & "muddy" feel, vs a single disc.
I notice it the most manuvering in a parking lot.
IMHO it is a small price to pay for the great holding power combined with the light clutch pedal.
Personally I can not stand a heavy old school drag-race -style clutch pedal.
Especially when there are great alternatives available.
It's standard equipment on a C7.
So you can even try one before you buy.
A single disc McLeod is very good. But may slip some under WOT with that TQ level.
The High HP solid discs on hubs without a marcel, have a very on & off feel, and are very difficult to slip smoothly.
Like off a stoplight.
They are even more difficult to drive, smoothly.

FWIW, most Motorcycle brands and models have OE Multi-plate clutches; HD have had OE multi-plate clutches far longer than most forum members have been breathing. Pre-unit Triumphs did as well. Yes, of course, limited space is a factor.

On my 69 I went with the newer Mcleod Street Extreme when the new engine was installed. I chose the Steel Flywheel because I was chicken to go lighter.
It holds the 650 HP just fine and reverse works without issue. Pedal effort is about the same as my moden cars.
