Does anyone now what a good clutch setup is for a 2000 mach z. Bone stock sled ive been told to load up the pins with more grams some say 20 to 22 grams. Any suggestions.

Maybe you could try a pink/white primary clutch srpring with 20 gram pins. Should work well with a 27 - 44 gearing setup. The secondary should be run with a 50/47 helix at about 20 lbs.
