Would love to hear what all is involved in getting a LS into these trucks and then still having to smog them. In California it's 1976-up. What are you guys doing for any performance mods? I'm considering a 5.3 into a 85 GMC and really annex on a stock engine but I'm thinking headers, a air intake and maybe a mild performance cam, something like the zo6 cam. What's the smog issues you guys have run into?
