My new engine was running strong, but fuel delivery was something that I was still struggling with. Bogging, stumbling off the line, sputtering, and very difficult to start no matter the temperature. Not to mention that I was averaging 10 mpg or less in town or hwy. The fumes of raw fuel filled my cab as I drove. I couldn't go anywhere without smelling like a gas pump. I finally decided to purchase a Sean Murphy Inductions Carburetor. I had known about SMI for some time, but had never been able to afford one of his carburetors. I pulled the trigger on his STAGE 2 ROCHESTER QUADRAJET. $350 shipping included. It took a little over two weeks to arrive, but was well worth the wait. It was like unwrapping a work of art. This carb was spotless, and everything moved and functioned so smoothly. I couldn't wait to install it. I had my friend Christian Install the Q-Jet, fuel lines, and new filter. Started right up, adjusted the idle / mixture screws and... Wow... That's what my truck is supposed to sound like. Smooth idle, smooth acceleration, quick response and no fuel wasted. The plume of unburned fuel had disappeared. My stumbles and stutters off the line were a distant memory. This carb feels as smooth as other fuel injected vehicles I've driven. My new MPG were far more impressive. On average I am getting 12 mpg in town and 16+ mpg on the hwy (2500 rpm / 65mph) I even saw hwy mileage climb to 17.4 for a 350 mile stretch. (must have had the wind to my back. LOL.
