The older JEEPS(those before 84, but after the war) were considered basically full-size. They offered them for a few years with a V-8 in the CJ's. The 6.5 weighs a little less than a big block chevy, but not much less. It would still be a little heavier than what you have now. There really isn't much out there lighter than your 304 in a diesel that will give you much giddyup. The 5 cylinder VOLVO is a pretty popular conversion engine, but not very powerful.
