i know its possible to swap a 350 into the first gen 2wd s10 blazers, and i did see an ls1 in a second gen. i have a 95 4 dr 4wd with over 170k miles on the questionable odometer, questionable miles on the ecm, and who knows how many on a questionable engine swap (it came from philly....). a friend of mine has a wrecked suburban, 350 4wd, and i wanted to see how difficult it would be to swap in the engine, trans, wiring harness, and ecm into mine. i would also like the factory gauges to work if possible, even if its needed to repin the connectors. i think his 'burban was 95 as well. i already converted to an electric fan and there is a good six inches from the water pump to the radiator. any help, tutorials, etc. is greatly appreciated
