I am planning to upgrade the drivetrain in my 42, 11/2ton 4x4 chevy. I'd like to use a 292 w/4L80 auto trans or Spicer 3035A 5sp od trans. Any suggestions?
Also, the Motors truck & diesel manual lists the 1970/71 292 engine at 170hp @4000 rpm, all later year models are rated between 120/130hp @3600 rpm. What's the difference, other than rpm, between these models.
