C2 Clutch Recommendation

Re: C2 Clutch Recommendation

Your floor flexed?

You must not have used the Centerforce clutch?

It has a heavier plate pressure and a light clutch pedal. Softer than stock.

I love my CF II clutch. The centrifugal weights do clatter a bit at idle.

But you can't beat the positive engagement and the easy pedal.

Nothing wrong with the LUK. But it will give your leg a harder workout than the CF II

Michael, I will email you tomorrow. I would like to talk with you a little more about this. Thanks, Mike

Re: C2 Clutch Recommendation

Hi Joe, Being I am so long in getting this car back together even though I went with a HP clutch setup all the components are NOS Gm for all the linkage and fork parts. I have had plenty of time to shop E-Bay over the years to locate all the parts. Glad I bough most years ago too. Thanks, Mike

Most of the clutch linkage parts except for the cross shaft remain available from GM. However, the 12-3/4" flywheel, pressure plate assembly, and 10.4" friction disc are long-gone. Those are critical parts of the assembly. The LUK parts are close.

Thanks Joe, I have a used original flywheel. I probably will have that surfaced and new ring gear installed and use that with the LUK. I appreciate you help, Mike

Gary,

No it wasn't your car.

But there was a clutch and ignition company in Huntinginton Beach CA (Hays) that gave me the clutch to test and the pressure was about 3800 lbs.

I think the stock pressurplate is about 1800 lbs.

What a waste, couldn't shift fast (power shift) because it took to much time to get the clutch to disengage.

DOM

The clamping force of the OE C2 small block clutch is about 2200 pounds. L36/68 2600, and L-72/71 2700.

The OE and LuK replacement are perfectly adequate for normal road and even road racing work, but not for 5000 rev clutch drop drag racing.

Re: C2 Clutch Recommendation

Michael, maybe before you instead of a new pressure plate you could consider this. It works, ive done it and like it. Scott

All------


The LUK unit I mentioned is equivalent to and a direct replacement for the original clutch. Therefore, its performance and pedal characteristics are similar to the original.

With a Corvette I do not recommend deviating very much from the original set-up. In fact, the best possible solution is a clutch system composed of all the original GM pieces. However, the major components are all discontinued now and difficult to find NOS.

Joe,

Does the LUK unit have the correct thickness TO bearing? I recall that some of the clutch kits have thicker TO bearings which cause issues with the clutch linkage adjustment. I would have to research the archives but may be a unique problem with 66 small block.

I'm not sure which bearing is supplied with the aforementioned kit. Most other Chevrolet applications which use the same clutch use the "long" bearing, so it's possible the kit contains the long bearing. The one required for Corvettes is 1-1/4" long ("thick"). This length bearing is used to SERVICE all 1957-81 Corvettes.
