Ok, first post, a question. And yes, I did search. Anyway, I just bought a 1983 GMC 3/4 ton 4x4 (350, 700R4)last week, and the carb is giving me fits! First thing, it's missing ALOT of parts, there are several "rods" that are missing, etc, etc. So, I'm thinking that I have one of two options. First, I can go to a junkyard and find another q-jet to put on it, and hope it's "ok". The second, is to purchase a Holley Spreadbore replacement, and go with that. (This isn't for offroad, I have another vehicle for offroad, this is my "towrig") So, basically I'm looking for something that's gonna give me good performance while towing, and won't give me fits. Any suggestions?
