ok i know this thing it heavy and the 460 only came with 230 hp and 390 tq.
my dad has a 91 f250 with the same set up. that thing moves. its faster than my 4.0 b2. and its fixed up.
heres what i know. mines has 3.55 gears. his has 4.10s. now is that, that big of a difference.
he has 265 75 16. i have 285 75 16.
i have a thrush welded muffler with the cat still intacked. he has no cat and giant hole in his muffler.
i just did plugs cap rotor coil. coil because the tip was falling off. new pressure regulator. mmo the intake. tires aired up to proper psi. brakes dont drag. new o2. and i know this causes a lot of drag but the previous owner installed a direct mount cooling fan to the water pump pully. i want to put a clutch fan or go electric.
now because his has 4.10s and small tires and weights 400 pounds less says the door tag. his blows mine away.
or am i having performance issues. no codes. starts with a mis that smooths out within a min or 2. checked for vacuum leaks. ran a bottle of b12 cemtool in the gas. im not sure if im having injector issues or not.
i cant seem to fine whats causing this lack of low end power. if someone can shed a little light on this for me i would greatly appreciated it. tia
