i've been running ram clutches for years. had good luck with them till now. 10 1/2" stuff, both 23 and 18 spline trans'. always used the 3200# pressure plate. started with the 300 series organic disc. now use 900 series sintered iron. i just smoke the clutch if i launch the car over 3500 rpm. sounds to me like you got a super light pressure plate or something. what you're describing sounds like my 72' challenger with a centerforce 2. the pedal was so soft in my '72 that my honda has more pedal pressure. i took out the over center spring and now it's perfect.
oh, the ram stuff is in my '74 challenger.
