Well... I didn't change the oil, and I STUPIDLY forgot to put the belt on my smog pumps when I got my truck tested today.
Guess what. I failed. but only the CO part of the "cruise" test (@2500rpm). Legal is 3%, I came in at 5%.
I've been busting my hump trying to figure out what I need as far as emissions controls to pass the visual, and I FINALLY found the answer. Since my truck is an 86 3/4 ton with Federal emissions on a 8510 lbs gross weight, it didn't come with cats from the factory. So I don't need them. So I won't get them. I've decided to go with a Flowmaster 30 series and 3" single exhaust. I know... everybody loves dual exhaust, but I just want it simple. Single 3" should provide plenty of flow, especially since once the gas leaves the manifold, the most restrictive piece is the muffler.
Now... I was planning on getting the carb looked at anyway, trying to increase fuel economy a little, and cold idle quality. Now I need to add CO @ cruise to the list of things to get fixed. It's a Rochester Quadrajet on the 360. There's a little electric thing I noticed on the side that looks like it's supposed to kick the idle up a little, but nothing is plugged into it. So I know there are issues with the setup.
Is the Rochester Q-jet a decent carb? Or would I be better off getting rid of it and putting a Holley, Webber, ???? on it? I'd rather not spend any more money than I have to, and I have to use an EPA approved mechanic for the work, so doing things myself isn't an option.
This is mainly addressed to those of you with 360s in your CJ, J-series, Wagoneer, etc.
Oh, BTW, is there any way to boost power without failing the emissions? I'd like to do whatever I can and pass, rather than pay for work now, pass, then pay for redoing stuff later. The 360 in the Wagoneer is supposed to have something like 144hp/265ft-lbs, which sounds a little pathetic. The Magnum 318 does better than that.
