  1. 4BT @350ft-lb Help

    Performance Discussion
    I'm wanting to swap my 4.2L V6 in my F150 for a 4BT. It has a M5R2 tranny and from what I have heard the M5R2 can handle 350ft-lbs of torque. What could be done to get the 4BT to about 350ft-lbs on a budget? I'm looking for a mild performance boost. I don't know if I will be running the engine...
