    No ****!!!!!! :no: I get 13 in town with my '96 5.7 (350)! Of course that's why I'm going to do a Cummins swap.

    Man, that's great for any 454. I wish I got that good in my 350.

    My '99 3/4 ton w/ 454 is getting 12+ mpg. Want to change the air intake system and exhaust next summer to try and get a little more.
