318 build suggestions?

Torque wise, even though I don't think it's a big deal, the torque probably be for a 400 ish hp engine.

318, 380-400 tq
340, 400-425 tq
360, 425-450 tq

Once you factor in the deeper gears and stall you should be running similar torque to the wheels, basically equals out, and if you don't want to run deeper (kind of a vague concept, deeper than what? Average?) then my signature fits "If your willing to gear it build it if not build a larger displacement, Or take solace in your compromises".
