    What's a good trans/ transfer for a big block swap? Truck in mind is a 73, building a 500+ ft/lb motor, prefer later model OD. Crossmember/driveshaft fab OK if needed...I'm new here, but chevyfumes is my weekend 'play trucks' bud (as his wife says). Have 4:10's, 35's, locker...Converter suggestions?

    If you prefer later model OD, and will be twisting with 500+ lbs of torque, you probably will want to run a 4L80E. They aren't cheap, but they will be up to the task. Jet Performance makes some nice ones, as does TCI and others. You will also need a computer to control it.

    Yeah, I agree. Use the 4L80E for your automatic choice and use the NV4500 for your manual choice.

    I would use either the NP205 t-case or the Atlas II, which has 2 options of low range.
