need help deciding
I have a 1992 f150 nite 2wd 5.0 I bought this truck off of my brother and we both like to race the Hondas and silverados we see around town. My brother put gt40 heads in and is telling me to put 3.73s that it will be alot faster I was wondering if this is true because his friend is willing to do it for 200 bucks so max I will spend is 550, I would like to know the pros and cons because I'm new to this truck scene
