List your MPG on your transplant 5.7 or 6.1

If you don't already hate me, my truck gets 25+ on the hiway and 17 - 18 around town... Thing is, it's a stock 330hp 5.7 lt1 chebby as you call them with a t56 six speed in a full size pick up and I too hit the throttle whenever I get a chance as well... :)
