Longhornmail,
You may be right on the horse power thing. I had a 86 305 HO TPI installed with no mods, it's bone stock, because as I said it is my everyday driver. I wanted gas milage instead of horse power. I can cruise at 75-80 at about 2500rpm's, and average about 20mpg with the ac on depending on if I'm out on the road are in town. In town I would guess it's a little less but I don't do to much of that, since I live out in the sticks of SC.
