I will agree that the actual CAUSE of crankwalk is not known. Yes, Chris Carreys motor did walk but he was also running a ACT 2900 so once again, that could have been a cause.

What people DO know, is that a lighter pressure plate will prolong the life of the thrust surface, which is why a Twin Disk is such a good idea on a built 7 bolt. I am not saying it is needed, because some people do fine on built 7 bolts for a long time. But the fact is, once again that NO one really truely knows what is causing walk on the 7 bolts. Many theorys are out there, but there is no definite answer.

Who knows, for a good price its probably worht it to try.......BUT I still would never build a 7 bolt or even put one in my car! When there is a better option out there (6bolt) for minimal amounts more work then why go with something that has proven to be unreliable.

And as far as Shanes, It seems like he has never gotten much over 200 miles on his built motors before something breaks or he decides to revamp his set up.
