I would hardly put a centerforce in the catergory of the best clutch out there , but thats me .
Herb , you are going to have to spend a pretty penny on a clutch to live behind that motor . But one thing you need to remember is its a clutch and its a WEAR ITEM , it's not going to last forever drag racing it .
Street twin and stop racing if you want it to last forever .
Figured that would be the answer. I bought a sfi flywheel last year and have heard that there is a street twin available that can be used behind my flywheel without buying a complete package. I hate to have to buy another flywheel again and would like to avoid it if it will live and work properly. John, I know that I am dealing with a wear item but would like to get a bit more wear out of it!

3.54 gears with ET radials and burn out starting in 2nd. gear.
This is probably a major item for taking your clutch out.
If you do take it back to the track,
start your burn out in 1.st just hold it steady at about 4K. I think you will see a lot longer clutch life.
good point , thats going to hurt it pretty quick , but he's got alot of torque so it should start pretty easy .
He needs to look at race clutch linings , they are harder to street drive but can handle being heated

For your application you need the disc as shown in the photo. It sounds like you have a regular style disc with a full marcel [s shaped spring in the middle of the disc] which does not hold up under adverse conditions.
The paddle disc has no marcel and uses metallic pucks which significantly reduces the release and lock up time when shifting...like night and day. As far as drivabilty with the paddle disc there are no issues as long as the concentricty of the b-h
is correct. There is a new metallic friction material avail now as well.
A custom clutch is what you need, if you want to go that route and end your pain:

Talk to Sam Jr he speaks mopar and clutch fluently
Tom, any thoughts on the dual disk setups? I see you road race your car and have read your posts in the past so believe you have some actual real world experiance. Not sure if you know what the centerforce looks like but here is a link to some pics of one. http://www.performancecenter.com/clutche...ssure-plate-kit
And the clutch guy is he in new york?

I used to fry clutches until I put a little more gear in the car.A 4.10 gear would be alot easier on the clutch.You are trying to move alot of weight with not much mechanical advantage so something has to give.If you love your transmission do not put a mega stiff clutch in front of it  I put a Street-Twin in my car and split a brand new Liberty 3-4 slider on the third pass.

I would say it's a great street clutch that NEVER slips but that is what makes it a bad clutch for a heavy drag car with good traction.There is another member here,Mike67net that had a major transmission failure just after he installed a twin in his drag car too.My new clutch has an adjustable plate that can be tightened up for the street and loosened for the track.The other issue I had with the twin was too much inertia for a crisp and clean power shift.With both of the discs and a floater in there it wont release quickly enough for a clean disengagement. And no they don't rattle. Gus
