I have a little project in the works and need a trans built. Looking for a 4wd TH400. My research on the interwebs has shown a bunch of transmission places that specialize in drag cars. They usually have 3 ratings up to 1000 HP, 1000-2000 HP, and 2000+ HP. The motor I'm using has 1285 HP to the flywheel so I need to be in the middle group. My requirements are pretty simple (I hope!). Reverse manual valve body, and 300m or better input and output. Any input would be appreciated.
