This is more like it. I'm running a very mild 357ci w/ dual 2.25" longtube header exhaust, performer intake, Sean Murphy Q-Jet, Open Air Filter, 275/60/15 tires... and with the addition of the 3.73 Posi and 700r4, I expect to do 15mpg or better... High hopes, I know, but I was doing that with my old tranny and rear.
