hey again.
i own a 1991 ford f150, 302, 4x4, red cab long box, automatic.
i want to get more low end power out of it.
i have a K and N air filter, 3 inch exhaust, and 8.5mm plug wires.
what else can i do to it that isnt gonna cost an arm and a leg??
the next thing i will be doing to it is some longtube headers and change my exhaust to dual 2 1/4" with magnaflow mufflers.

 

Other ideas would be removing the AC and replacing the rear-end. Removing the AC is probably the cheapest route. Are you looking for more horse power or torque?

 

if sound wouldnt b an issue just change the headers and straight pipe it and get a computer chip
