TomERA Tom I am using a GM clutch from centerforce. I REMOVED the wieghts because the thing wouldn't shift over 3500 rpm. The lockup on the pressure plate caused this problem. Your clutch may be drilled for both 11" clutches. I go racing once a year and it is very hard on the clutch so if it blows, I have to options, Ford or GM to fine parts to fix the car. I am not limited to just Ford. Have had no problem with the setup in 5 years.
Just a burning smell after 1/4 mile runs
It's all good. Rick Lake
