I have a 98 Chevy k1500 that currently has a 5.7 vortec. I would like to do a diesel swap into it. I am looking for something that would do great on mpg but would also be able to tow as well. I wouldn’t tow more that 5-7 times a year and the most I would tow would be a boat or small camper. Camper weighs 2300lbs and a boat roughly 4-5,000lbs. If someone could help me decide what’s the best rout for a diesel swap. Would a 4bt Cummins do the job for something like this without having to swap to 3/4 ton axles and stuff like that?
