904??
I've been using the 904 for about 20 years now. The 904 can be a quality race transmission! If your Mopar is 3000+ lbs, the three speed is what you want. Especially being a small block! There are many quality manufacture's of the 904 parts. May I suggest aluminum internal components. [drums/servo pistons and output shaft support assemblies.] A person can spend many $$$ on the 904, but reliability is impressive/very good! I know of many vehicles now running deep into the 9 second range with 904's! And a few of these vehicles weigh as much as 3400 to 3600 lbs! My combination is almost 650 hp with over 600 lbs/ft of torque! I have not had a transmission failure...period! I have installed new clutches, and a second gear band only because of wear NOT because of failure. All being told. the 904 is a "positive" move for one looking to improve on ET and MPH. I use one source and one source only, A & A transmission's parts/pieces to move my Dart down the 1320!
