Ok all you Ford goers, Let's see if some one can help me with what might be wrong with my old pickem up, I have a 1985 F-150, 5.0L/302 w/AOD trans. Just put on new headers and exhaust, wires, plugs, rotor & cap, new carb. Even with the old stuff on, the truck would not go over 65 MPH and with the new stuff it still does't. So I took it to the shop and they disconnected the electrical connections to the carb and advanced the timing and adjusted the carb. It runs better, but I still bearly get to 70 MPH after that. Is there any thing I can do to get it running faster on the highway? Oh I am also only getting about 8 MPG, I should be getting at least 12 - 15 MPG. Well there it is, if any one can help Please let me know.
Hey guys thanks for reply's, I do have a new fuel filter, when I took it to a shop out here they said I was getting plenty of pressure and volume. I do have a new air & breather filters & PCV. Now the breather filter does have some oil on it. As far as timing the shop set it, he said he advanced it a little, how much I don't know. Tires, I have 31 x 10.50 - 15's, Gears in it I have no idea.
