The Ford Barn - View Single Post - Lincoln ECU Alternate Transmission Options

IF I do change to an AOD, I was planning to go with a Ford(Lincoln) 9" with somewhere between 3.7 & 3.89 ratio gears(maybe 4.11?) to not lug the engine. With a stock cam they like to cruise somewhere near 2100 to 2300, which is well into their torque curve. I have to ask how well those RPM numbers "fit" with any of the Transmission options you've suggested? I'm not looking for speed/power, as roughly 300HP is plenty for a "driver", but am trying to get more than 16mpg! Instead of an AOD transmission, should I remove that infamous "Teapot Holley", & hide a modern EFI under the huge air cleaner? A lot easier(& way cheaper) than the transmission changes!
