I own a 97 Chevy 1500 4.3 V6 vortec. Everything is stock on it. It has 142000 miles and i want to get a little more oomph and gas mileage. Hell, ill settle for mileage and no power right now. Anyone have any suggestions. I was thinking KN filter. I dont want to spend a lot, ie: get a new exhaust or engine. just a couple of hundred dollars.and yes, i know its its a puny V6, but i a m planning on getting something bigger int the next few years.
