Re: 1987 350tbi smog delete. What needs to be removed, plugged or any of that good st

Stuff usually good to leave on a street truck:
PCV: Really helps keep the oil clean by pulling the blow by out of the crankcase. Most carbs and injections systems are calibrated for the presence of PCV.
THERMAC: helps with cold weather warmup and lessens the chance of carb icing in cool humid weather. A modern computer/injector system may not need.
Charcoal canister for gas tank vent. Those gas fumes are going somewhere, might as well use the factory system. Doesn't mean you can't move it to a out of the way spot in the engine bay.
Did you keep the O2 sensor?
