Jerry,

Believe it or not, with a fresh super tune I was getting 15 1/2 MPG Hi-way with my 305 V-6 that I had in a 1/2 Ton Pick-up.

Now I also drove a 478 V-6. Not bad for what the truck was, but I believe that one was getting an all around 7 to 9.

Also drove a 637 V-8. We figured that one around 5 to 7.
