Shitty fuel milage
Ok before i start i just wanna state that when i built this motor i had no intensions on having great gas milage.i just wanna run this by you guys and see what you think..i filled up 5 days ago and again today. my trip milage was at 180 and the needle was on the red. took 15 gal to fill up..so im figuring 12 mpg correct..now for my setup..383s with TEA5.3L 1.5 heads, TREX, LT's with no cats duals, svo 30lbs, warlbro fuel pump,a4 with 3500 stall..i pulled 420rwhp and fuel ratio was damn near 13 all the was across..i can post the dyno graph if you need it or if you have any other questions on my mods to further guestimate my milage please let me know...thanks abunch..and again its not that im worried about MPG just curious if this is about right.

Really depends how heavy your foot is...although that seems a little low to me. If you have the ability to monitor your AFR I would try and ensure that you are around 14.7:1 most of the time while cruising...My mileage was better then that through a non-lockup TH400 and heavy *** drivetrain with 60lb. injectors and a 403ci motor.
