I'm not sure which forum to post on so please re-direct meif I'm in the wrong area. I have a 78 3/4 ton 4x4, its getting tired. I would love to upgrade the 350 eng. trans combo with something better. I mainly use the truck for off road and some minor trailer towing. I think a rebuilt engine would work but what carb is good to use (smog is not an issue). What is a good tranny to use? My background is old jeeps, not up on trucks, please help.
