do these things have no power? i have a 91 f150 4x4 regular cab long bed with 33x12.50-15lt baja mtz tires on 15x10 rims. truck has 72,000 miles on it, it just seems like i have no power. dont get me wrong it doesnt fall on its face when you step on it, but it just seems as if it doesn't have what i think it should. seems worse in 4x4 than in regular 2 wheel. thank you in advance, all input is helpful

 

With all the emission crap, efi crap and factory cam retard the windsors are slugs. mass air and a better cam would wake the engine up.
