Re: Weber or Howell?????
I agree the Carter option mentioned is an inexpensive way out. But if you are looking to improve gas mileage, power, and driveability, the Howell system is the way to go.
I HAD a Weber for a couple of years on my 4.2, and I could never tune it in right, even after re-jetting and fiddling for endless hours. On top of that the performance on steep hills suffered (going up a steep dune), and the fuel mileage was horrible. I switched to the Howell TBI and I have never been more happy with any of my upgrades.
Howell if you have the money, Carter if not. No to the Weber.
Side note: do the TR cap and rotor (81 Ford F150 cap rotor and cap adaptor) under any circumstances. Very cheap and a good upgrade. I did this, but I also run an MSD, and an MSD coil. The factory ignition and computer are totally gone replaced by the TBI brain and the MSD ignition. Good combo in my opinion.
