You may have to change a few things like radiator and exhaust.

If you currently have a 4.3L then you must have the T15 Jimmy (not full size). That vehicle never came with a 350 option so to get it to work will require that the entire computer system and wiring harness be changed, the radiator and cooling system increased, the transmission may fit but probably won't last long if it does, the suspension wasn't built for the weight of the V8 so that will need to be changed, the fuel routings will need to be changed, probably the fuel pump too, the list goes on and on. Oh yeah - that would also be considered tampering with federal emission components and is against the law. Best bet - go buy a full size vehicle that came with a 350 - it will be a lot cheaper!

you shouldnt have to do anything other than dismounting the other engine and dropping the 350 in. the cassis is already made to support a 350 small block. if you were to drop in a big block you would have to do some rebuilding to the cassis but if just a 350 then no. just drop it in.

TO PUT A V8 INTO THE JIMMY YOU WILL NEED TO RAISE THE BODY TO CLEAR THE FIREWALL OR YOU WILL HAVE TO CUT IT BUT IT IS BETTER TO RAISE ALSO YOU WILL NEED HEADERS THAT CLEAR AND BEEF UP SUSPENSION MOST OF YOUR 4X4 PLACES CAN ORDER OR TELL YOU WHAT YOU WILL NEED
