I have a 99 Ford ranger 3.0L V6 with the flex fuel option. Currently Im getting kinda irritated with it because when the engine is under load (going up a hill) it has nasty pings. I figured I might be able to get a head with larger valves, performance cam shaft, larger injectors, and maybe a larger fuel pump. I was wondering if this upgrade was reasonable or even duable on a flex fuel capable truck? And would I be gettin rid of the pings and gettin good horsepower for my buck?
