[66StangGuy]

well actually i dont have the 3.55's yet. my car is up on jackstands because i took my old 2.80's out and found that there were 10 broken teen on them. So i bought 3.55's and just put it in my signature eventhough the gears are still in the mail. i was just wondering how much lower my mpg would go from the 2.80's to the 3.55's.

Also i do like to go fast and thats mostly the reason i bought the mustang and had an engine built just for my car but i think i also need to work on the carb a little. i think i need smaller jets for it because i lose power after about half throttle. i think its just running too rich but im waiting to get a air-fuel sensor anyway so thatway i can be for sure and get everything right without guessing. sorry for the confution.
