This is the last time you can decide on a clean sheet of paper whether any Chrysler is suitable w/r/t strength, weight, size, ratio choices, expense. "mostly strip use": would O/D be useful? My DD has .705 O/D and 3.77:1 axle = 2.66:1 overall ratio, and wish I could slow the engine down even more but $$$. Please note: IIRC 727 has a drum & band (70 year old design), TH has only clutches. inherently less dangerous.
