I need some recommendations for a clutch to put in my street/strip car.
This clutch needs to launch and hold good on the drag strip, release clean at 7000 rpm for quick shifts, and be somewhat streetable, and very reliable. My theory is to use good parts, not something iffy, that might work. I don't want to go to all the time and expense, just to drop out of a race because I bought a part that wasn't up to the job.
I have been using Mcleod and Advance soft locks in my other race car, but would prefer NOT to use an adjustable clutch in this car so I don't have to adjust it every time I transition from street to strip. Further, I have an adjustable softlock from another project that I test fitted, and the counterweights on the levers won't clear the Quicktime bellhousing. With the Quicktime, it is also limited to a 130 tooth flywheel.
I am considering setting up a "hillbilly softlock". http://grannys.tripod.com/clutchtamerdiy.html

The car is a 31 Plymouth coupe with a 4 link. It is still under construction, but I estimate it will weigh #3000. The engine is a stroker 469 early Hemi.(1st gen). According to Pipemax, it will make 600-650 horse. (I have no idea how accurate that program is, that could be a Pipedream) The trans is a Tremec T-56 Magnum, with a hydraulic release. The rear gear will probably be 4.20, and the tires 30" quicktime pro bias plys.

So what clutch is the hot ticket?
Thanks, Joel
