I have a McLeod Street Twin in my 71 Challenger, 470", 600HP, aluminum Hemi 4 speed, Dana 3.54
Its the only clutch that would hold up. I went through 3 other setups. Only thing is it's, how do I say, grabby. If I'm not careful leaving a stoplight my car will launch 1/2 way through the intersection. Luckily the BB has enough torque to not stall if I release the clutch with very little throttle cause you can't really slip this clutch.
I'm very satisfied with it but I wouldn't throw the keys to just anyone to drive it
