IF this were I, I would use the 4spd trans. A 245/60/15 wheel & tire. (27 inch max tire diameter!) I'd skip the Hyd. roller cam myself. Umless you have a Magnum engine.
A cam duration @ .050 of 224 (-ish), 1.6 rockers, valve springs to match. (Call me crazy, but to expand the camshafts flexibility...) Top of the line Rhodes lifters, (Also available for the Chrysler Hyd. roller cam) adjustable duration units set at the max on the intake. Stock lifter on the exhaust.
OE or Edelbrock Performer intake. 650 cfm carb.
