Hey there. I'll drop mine in here too, 'cause. Most of what goin' on here sounds like good advice, but I wouldn't worry too much about the "computer" on that '86 burban. It's pretty much just a body computer. That is is doesn't actually run much on the engine, just takes readings, pretty much. The carb you're talkin' about, if Im not mistaken, is the early electric carb and it's about the only "computer" controlled component on the engine itself.

'86, standard old HEI I'm guessin? Those 2 wires on the carb are still technicall a TPS so that would be the only problem I would forsee. The carb won't respond as well as with the box. Other than that you should be able to dump the air pump, O2 sensors, etc... and have no problems. On the up side that is still a quad intake so an earlier model would fit no prob and you would still see the benefits of "stock" asspiration, ie: better mileage and good all around performance.

I'm glad to see everything spec'd out good. Should be a great mill for that G body.
