The best I've ever done was about an 11-4.
The first started out with a heavy duty AutoZone diaphragm clutch that lasted through my 318 and into my Stroker motor before it started slipping in 4th Gear at the top of the track. Then I figured I'd solve that slipping problem once and for all with a act technology six puck clutch. That quickly took care of the eight and three-quarter that I built. I built a Dana 60 and now I slip a Hays clutch disc in that act technology throw out plate. All a terrible setup nothing to definitely recommend. Of course people talk more about the bog Warner clutch and being able to set up a certain amount of pressure and all that. This year I plan to leave the Slicks off the car and let the tires slip a little and try and be consistent and not break stuff. Honestly every time I look at your thread and see all the stuff you did to your motor it boggles my mind. If I had any advice it would be keep it simple. Any specific ideas on clutching from me would only be on what not to do.
