Finally took the clutch out. The clutch disc has two cracks in it. The flywheel has some blue and hair lines cracks on the surface. The pressure plate has metal sort of smudged as if it got hot and moved. I think I lost pedal because the disc is very thin about an eight inch of material on each side. There is some oil inside the bell housing. I don't know where it came from. Does a Muncie have a front seal? or just the drain back hole, and is this hole positioned so it is on the top of the transmission?
I had synthetic oil in engine for a while, but it leaked thru my cork gaskets. My roller rockers sounded like they were going to come apart. I went to regular oil and it seems to work alot better.
The clutch itself is dry. Could oil have gotten on the plates. My leaks a litte, about the size of a fifty cent piece after I have run it for awhile. Why would the disc have two cracks in it. I am running N 50 MTs with a 3:73 gear and 455 app 450 horse. This Center Force dual friction clutch was supposed to be good up to 600 horse. The car has never been to the track either. Just some runs on pavement. Tommorrow I am calling Center Force and getting their oppinion.
Any experiences or help will be appreciated.
