i remember the old Green Cover (3100#), i thought they worked the best, but can't find them anymore.
asbestos disc worked way better than the organic's of today , but are no longer produced

what are drag racer's using today at the strip on slicks?

car will weigh around 3400#, mini tubbed with 16" of room for tires

I use Center Force dual in my built 440.Has been in for like 15 years and still works great.Some like them some dont.Love mine.Had a Mccleod 3500 B&B in it for years.CF holds better and light pressure.Some complain that they dont engage easy.I say BS.Never a problem.Even with the M&Hs it still worked perfect.Rocky

I have a McLeod dual disc setup behind my 472 Hemi. A bit harder to drive than the Borg & Beck I had behind the 440 that was in it before as it seems to be more of an on/off clutch. But I bought it to hold up behind the Hemi.

I have the McLeod twin disc behind my 528 Hemi. I've had it in for two years now and it's worked great for me.

Currently using an 11" Centerforce DF behind a 470 with an 18 spline. Street driven, E-body, 3450 lbs., 4:10 / 3:55 with 9" x 28" slicks. Still holding strong after 12+ years of casual street driving and 50-60, test and tune, quarter mile runs on it. I have used Borg and Beck style clutches in the past. However, this is my first diaphragm type setup. Recently read about a "Clutchtamer" device which has peaked my interest. Seems like several clutch manufactures offer quality options.
