THis is a very well covered topic, if you search.
My comment on the TFS kit would be that I installed it with a different cam. The person I spoke with at the TFS tech line explained that the cam that comes with the kit is really designed for the fox body computer. Our computer has trouble with this cam. So he directed me to Anderson FOrd Motorsport (where I got the B-31 cam). And Trickflow substitutued a TB elbow and intake spacer for the cam, in the kit.
With the B-31 cam, I ended up with a nice idle, without resorting to any computer/chip/EEC tuning. I plan to eventually do a PMS to tune for maximum power, but it runs fine for now.
Mine is a 5 speed, so I can't comment on the AODE driveability question.
