Re: Just how easy is a 4.3 to 305 swap?
tbi's do too have computers... it is right behind your glove box... i just put a carbed 350 in my 89. ripped all the crap out... to bad needed the computer for abs brakes and lockout on the tranny, but i don't care. made my motor mounts. have to modifiy the oil pan... or buy a custom one ($200-$250). depending on how you mount it, you will need to modifity your drive shafts, need some electric fans, possibly a better radiator. as for headers, i used headman 2wd shorties ($110). have to cut the shock tower for clearance, and suppose to do something with the steering shaft, but i didn't... also, they run a little close to the fuel lines, but it should be ok. i left my tranny and all that stuff in the stock location, and just set the motor in the truck, bolted that stuff up, then welded my mounts in... so i have 2 pusher fans on the front of the radiator, no room for anything on the back, and it will get a little warm at idle, but is fince driving.... think it is mainly from the mechanical temp guage getting hot form the stagnet air in the engine compartment...
