I converted the 88 EFI 460 to a carb when i swapped it in my 84 Bronco. Your biggest problem will be dealing with the computer-controlled E40D auto tranny if you have that. Since the fuel injection system runs alot higher pressure than a carb, your stock fuel lines will need to be changed, either converting the motor to a manual fuel pump or installing an electric one with low ressure (5-7 psi). You'll also need to change the intake manifold and distributor to one compatible with a carb. Since my 84 was originally carbed, I din't have to worry about changing the fuel system, and could have left it alone. But with an original ,leaky rusted tank and lines, I replace it all with a 15-gal fuel cell, electric fuel pump, pressure regulator and new, braided steel hoses with -AN fittings. Also installed a fuel pump safety switch that operated the pump only when the motor has oil pressure, so the pump doesn't keep running when the engien is shut off. JSM84
