Ok guys I am trying to get my sons 86 k10 going for his 16th birthday next week and have some questions. First off let me start by saying the po of this truck put a later model center bolt valve cover engine ( I think and 89) in the truck and at evey turn I find something that is rigged or not hooked up and it's making more headaches for me. I am going back with a early model 350 crate engine that I bought. My problem is I want to use all the dash gauges that are in the truck for now so I guess my question is since the later model engine has different placement for temp and oil pressure and they are all electric what are my options? I am going to head to the parts house later today and see what I can get for sending units. Any help would be great.
