First we need to make sure it is a 5.8ltr so please give the info I need to figure that out. Make the measurment that I need. This will help a lot. You do not have a transmission modulator valve, it is controled buy a spring inside. I had an 89 F-150 same as you just a truck it had a 5.0 ltr with the AOD and when I put in a shift kit the shift firmness was based off of what sping I put in it above the valve body. You can not put a big cam in your bronco the computer can not do it and not can a chipped one I have been there. Ford does make a mass air flow kit to put on that bronco at the tune of $800 then you could put in a bigger cam.
Now if you would give the measurment that I need and do you know what year 5.8 ltr engine he said you put in?
