I've been reading a lot on the 4BT Cummins engine. 3.9 liter, 4-cylinder, 105-120hp, gobs of torque, can mate up to all sorts of transmissions. They are typically found in step vans (bread vans and the like) and are a pretty good size for swapping into everything from full-size pickups to Jeeps to RV's.

Anyone on this board ever put a 4BT into their C/K truck?

Not a Chevy truck.
I put one in a 88 Toyota 4x4 about four years ago. I got the engine cheap because it had 270K on it, I planned on rebuilding it later when funds became available but sold the truck instead to a friend of mine. He uses it as a daily driver and has 420K on it without a rebuild.
It's a great little engine but may be a little underpowered for a fullsize truck.
