Fuel Injection To Carb. What Guages Will Still Work?

[BowTie Eater 5 Liter]

Its been a long time since ive been on here, but i always got good information.

i have a 90 ford f150 short box, single cab, 4 speed od, 4x4, lifted 8 inches, on 35x12.5's, warn winch, winch bumper, light bar on the roof, canopy, 7 off road lights, but the thing i dont understang and need help with the most is the motor.

apparently it is a 71 or so mustang ho, high compression 302. the truck was converted to carb, but the motor was switched over to the serpentine belt. the truck goes pretty good for a big heavy truck(i beat a friends 5.0 thunderbird, a 5.0 explorer).

some of the electrical guages do not work(tach, oil pressure, temp, and the gas guage, but the gas is just the sender unit) because of how they switched it to carb.

does anybody know which guages i can hook up to work properly, and how i would go about doing so?

thanks for any help.
