Wow, I didn't think I would ever hear someone talking about those again. I had a front engined dragster with a injected BBC and a clutchflite tranny years ago. I used to have to rebuild that thing after every three passes. I used a sintered iron disc, and the pressure plate had weights on the outside edges of the fingers that would put more pressure on the disc the higher the rpm got. I could never get the rpm on the engine up very high before leaving the line cause as the rpm got higher it would push my foot up and engage the clutch. Got that car into the low 9's before selling it. They are very simple to rebuild. I think the bell housing was made by B&M. It was too long ago to remember where I got everything though, but thanks for reminding me of a time when drag racing was easy.
