Hey guys (I am a new member here, excited to have a site like this here!), I am in the process of acquiring a '88 (or 89?) Chevrolet 3500. My goal of this truck to to have a dependable unit capable of pulling my race car (pic below)..at some point I might be pulling it with a enclosed trailer... There is currently no engine or trans in it...I have a extra TH-400 with a bolt on yoke I will put to use. I am weighing in my options of a engine. I am thinking of a SBC 350 but I know these came with TBI so do I need any different heads? maybe a LS engine? or are there a lot of headaches converting it? What is the diff that came in these? I looked it up a bit and it seems like a Dana 44 or 60? (I included a pic..) Where can I get a service manual? I am just trying to learn as much as I can. I started on the rear brakes and found out I need a special socket to remove those massive drums! lots of plans!
