Fuel starving
Have a 1966 galaxie 500XL I put a 1972 302 in it
and it's been great to me so far. I recently added a
3in rear lift on the car to stance it out a bit. After I
did that, it wouldn't go over 55-60 mph. I put a new
fuel pump on it, fuel filter and check the line. I
cleaned the carb out took it apart made sure
everything was in order and put it back on. Runs
great up till 55-60 then it starts to sputter and die.
I've also checked for vaccume leaks found none.
Any ideas?
