I have a 1958 Edsel, basically the same as a '58 Fairlane with the old FE block. I am thinking of swapping out to the 6.2L. Will any modular automatic transmission work with it or only the 6 speed? I also have 9 inch with high 2.91 gears, should I lower the gears a bit, say 3.10 or lower? Think basic freeway/town driving. I've checked and while the horsepower is more, the torque is the same. I have also heard about swapping out chips in the computer for better horsepower and gas mileage so any info would be greatly appreciated.
Don't too hard on us Edsel guys as those engines found their way into Mustangs in the late 60's and early 70's so the information can also help those guys, too!
