bad carb???
I HAVE A 77 F-250 4X4 WITH A 351M/4OO AND HAVE A LITTLE PROBLEM. WHEN I AM ON THE BACK ROADS GOING ABOUT 45MPH IT RUNS GREAT. BUT WHEN I GO TO GET ON THE HIGHWAY I HAVE A HARD TIME GETTING IT UP TO 70MPH. IF I FLOOR IT IS SEEMS LIKE IT FLOODS OUT OR SOMTHING IT KINDA SMELLS GASY. BUT IF I USE 3/4 THROTTLE IT WILL GET TO 70 QUICKER THAN FLOORING IT I CHANGED BOTH FUEL FILTERS AND IT STILL DOES IT. OPEN FOR SUGGESTIONS 89 FORD MUSTANG LX 5.0 SPECTATOR ELIMINATOR

Snake: It sounds to me like you mayhave a bad power valve. It is in the bottom of the carb bowl, if you have a 2V carb. You might want to put another kit in it just to make sure all is OK, they re not that expensive. Most of the time, you don't even need to make adustments except to the float, if you are careful to put it back exactly as you took it apart.
You didn't say what kind of carb it is?

Mr.Brownsnake I found out also that it could be accel. pump I kinda dought it thou. The intakes are not interchangeable between the 460 and the 351m/400 so i'd put a 4brrl. intake with the 600 edelbrock and be done with it. You can get intake from Chris or Prankes for little to nothing. It would be easier on gas and more power also.
