I'm curious. Would it be possible to do a diesel conversion on a 1978 Sierra 15(1500)? I'm thinking either a Cat or Cummins mechanical diesel, beefing up the transmission and rear-end, and maybe converting to 4wd. I really like this truck but the engine, transmission, and rear-end are pretty much gone. I figured a massive rebuild like this would be a good practice run for when I restore the 59 Ford Fairlane 500 my grandfather bought new right before he died.
