Re: mileage and other questions

I have a 1996 GMC Sonoma 4x4. It has the 4.3, 4L60E auto combo and gets 16MPG. I expected closer to 20MPG when i bought it. I've been considering replacing the 4.3 with a 350 but i want to keep it fuel injected. I just had to have the trans rebuilt so i'm considering getting a 350 vortec motor, ECM, and wiring harness out of a 1/2 ton with a auto trans and swapping it. I think with the extra power and the lite little truck it should actually do better on MPG. I might be wrong on that since i have a heavy right foot LOL. Jason
