Hey y'all I'm new to the site n to swapping motors but I'm not new to turning wrenches haha.. I joined here to find more info on swapping a ls (lm7) into my 94 c3500 cclb.. Just want to see what I can do to the truck with the tired 350tbi in it yet that can just start working when the ls goes in, like fuel system n anything else that will work with both the 350 n the lm7 I'm planning on putting in..
