I am planning out my build up of my 83 FJ60 - 233k miles, bad clutch, needs engine rebuild, tires, rusty. I was going to rebuild everything, frame up. I am thinking of doing a 350 conversion. I am going to rebuild all the axles, tcase, etc. - not sure what I want to do for an engine/tranny yet, still deciding. In looking for an engine on craigslist.org I found whole suburbans (1/2 ton and 3/4 ton) for like $800 to $1500. Some with 454's, some even have 35" tires included. Since I have to rebuild all toyota stuff (seals, bearings, etc.), would it just be cheaper to get a donor chevy vehicle and swap everything over - engine, tranny, tcase, axles? It has to be cheaper to rebuild all this stuff and it cuts the need for adapters out. Thoughts? anyone done this? What vehicle would be the best donor, or would it be better to try and cobble it all together?
