I am putting a 86-87 3.8 into my 92 Camaro. It will basically be a TTA. I want to know what I should do after I get it running and on the road. The first thing I plan on doing is a full and complete tune up. New liquids, wires, and the works. It will already have a Flowmaster catback on it. So what should be the first few mods I should do just to get her running strong?
