What is the size of the 4bbl you have? The 4 can be more efficient than the 2 if you keep your foot out of it. Make sure its not too large.

I have a 500cfm with a performer intake, TH350, 3.08 gears and I get 13mpg in town. I dont do the highway much so I dont have a figure for that.

a 650 will be way too much!! I had one on mine and you could almost see the fuel coming out of the tail pipes. I went down to a 500 and had more power and better milage.
