Being an ex-Passon customer.. I cant give a strong enough recommendation, he is a GREAT guy to work with.. Without going into details, I bought an 18 spline Hemi 833-OD, screwed it up and Jamie bailed me out. Keissler would have never done that..

The only advantage I see to Keissler is the extra gear.. Since I race the Duster, it would have been nice to have four true gears and then the 5th as an OD.. With the 833, you have a 3 speed transmission and a OD..

BTW.. the only reason I am an EX-Passon customer is because I swapped to a full race auto 727.
