Hello. I'm brand new to the forum so I apologize if I've posted in the wrong thread. I am the proud owner of a 1986 chevy c20 Silverado 3/4 ton long bed with the ever so Eco friendly 454. The truck is carb'd, factory no cats and no computer of any kind. It has two smog pumps, one on top of the motor and one on the bottom left that push air into the manifolds. I really would like to remove these pumps as I'm sure they rob quite a few horses and clutter up the engine. So my question would be will this be a smart removal or would this cause and issue with gas mileage or something worse?
