After years of wondering about the possible consequences of my actions, those of removing all my smog stuff and eventually the entire motor, I called the engineer at the Division of Air Quality in the Utah County Health Department. His answers surprised me. Basicly, anything made between 1969 and 1988 has to retain only two items and that's only if they came from the factory with those items; an air pump and a cat. He said you can't go backwards, like putting a carb on something that was fuel injected, but you can certainly go the other way. EGR is not something they care about. So I confessed that I had been running a V8 in the rig that originally came with an I6 but that it gets better milage and the emissions are actually better, and he though that was great! All of this was caused by some twit at the place where I got my emissions done (it passes at the pipe). He said the county had mobile rigs that tested vehicle emissions at the roadside with a lazer of some sort, and if you get tripped up by that thing, you're going to the county for a complete inspection. So I got worried. Well, they were doing this but they aren't anymore and besides, all I lack is an air pump to be perfectly legal which I could get if I had to. Ahh, the relief!
