ok, change the disc. mcloed series 300 disc will be your best bet. A B&B pressure plate at 2200 to 2400, will make it work good, I run a stick shift 340 stocker, I've ran that style clutch before, now I have a soft loc style, have the pressure plate checked for warp. it's probable warped bad. same with flywheel, I've ran clutch cars for over 50 years.
