1990 F250 460
I recently motor swapped my 1990 F250 with
a 460, to a 1991 460 of the same type. The
motor ran great in the parts truck, but as
soon as I put it in mine It will only start on
ether and won’t idle, I have to feather the gas
for it to even attempt to run. I am completely
stumped. Any help would be appreciated.
