Hey all. My name is Ryan. I've had my 1987 silverado since I was 15. 26 now. I am looking into drastically redoing the whole thing. I work on cars for a living so I know my way around them. Except not the older stuff. Intro to the truck. I took the fuel injection out and put a carb 350 in when the engine went. It is a standard cab short box 1500. I want to put a 454 and 3/4 ton axles under to help handle the power. I am going to be doing a lot of body work too. Now the questions. WHat year 454 should I look for? what axles? Should I just look for a donor truck that is rust free? ( I live in Michigan) How do I identify what is on my truck now? Thanks.
