A friend, with a '74, has had a Tilton Dual Disc for a few years. His words, "It's a quality product". He has 502 HP, and takes an occasional trip to the track. Runs 11:6 in the quarter. The Tilton Dual Disc was the only one that would hold the horsepower on launch.

The linked thread contains lots of helpful, credible info; I looked, but found NO Reference to any TILTON Clutch.

I looked on their website and I can’t really see anything listed for these cars.
I called yesterday afternoon and hopefully will get a call back from them today about what setup will work with a ‘68 4 speed big block.
Any information/ part number would be greatly appreciated.
Thanks!

Which ever clutch you use, make sure it passes the 1/2" finger movement test to generate clutch release.
There are a variety of clutches on the market that do not, and cause grinding problems in corvettes.
FWIW a friend had two different height Tilton hydraulic release bearings, in and out multiple times (7?), and still could not get a clean clutch release.
Neither of the release bearings had enough throw. They were designed for manual adjustment, in race cars.
No quantity of shims would fix the issue.
It was a custom build, with a custom frame and a mish-mash of almost 100% expensive aftermarket parts.
Nothing was factory.
It had many installation issues, on many of the components.
During the install process, he refused to buy a release different bearing, or measure the clutch release.
The real problem still remains unresolved, and the (stunning) build is undriveable to this day.
He resorted to starting it in gear just to move it around, and basically smoking the clutch.
It could easily have been a mis-match between the LUK clutch pedal assembly and the clutch itself.
Sad.
At least we were able to get the wheels to roll.
The pads were locked up on the 15" two piece rotor bolts, etc.
It all looked fabulous, but nothing fit right.

OP 9forty:
Yours may or may not be a good candidate for Tilton clutches. Perhaps a different clutch would suit better ? Tell us a few bare facts about yours, please ?
What is credible max HP and max TQ you believe yours achieves ?
What is primary usage of your vehicle ?

427 being rebuilt with HP projected to be in the neighborhood of 550-600 and Torque 500+
It will be a street car… spirited driving from time to time but nothing where I will be dumping the clutch with regularity.

Suggest look toward McLeod's Dual-Disc clutches.

I was looking at the McLeod dual disc and the one that McLeod said was for my car (6911-04) is not showing up as compatible for my car on the Summit website.
Can anyone confirm this as being the correct clutch for a ‘67 Muncie M21 10 spline and 168 tooth flywheel? (6911-04)
Thanks!

Of course I’ll take McLeod’s advice over the Summit website but I was wondering if someone here can confirm that this is the correct clutch for this application… just out of curiosity.

I indeed called McLeod first because I could not see anything on summit at first for my setup… the Tech told me the 6911-04 was the one for my setup, so I went back to the summit website to order it and it said it was not compatible for my setup.

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 have even measured it.
Just make sure you get 10 spline discs, that's all.
Otherwise it's just a 11" dia. chevy clutch..
