Anyone running a 904 behind a 340?

My point was that just upgrading the sprag is not the be all to end all, especially when you look at what they were originally designed to do.
A lot of people think that just going to a TCI bolt in sprag will immunize them form having a sprag failure, when obviously it won't.
Agreed !! My 904 has the ati 30 element sprag, an aluminum front drum and a billet brake that leaves the band on till 2nd gear, solid a&a low reverse servo kit to speed release and John Copes recommendation for a double wrap low band adjustment of 1-1/2 turns versus the factory 4 turns to speed the release of the band.
