I put in an engine this weekend that I got from a salvage and after I got it installed found out it knocks. Long story short the guy tried to blow me off and not make good on the engine he said he would warranty. He tried to pawn off some other crap engines on me but I would not go for it. I saw they had a 1990 model chevy truck out front for sale. He said he would not part out the truck but after I changed his mind with some persuasive words I'm suppose to go pick it up tommorrow. What all am I going to need to get besides the computer to make this thing work in my 1977 Jimmy? He said he would give me what ever I need off of it for my troubles. I just don't want to get a bunch of stuff that I will just end up throwing away. Thanks for your help.
