Re: EFI 5.0 Horsepower?
EFI 302. You'll need to convert to Mass Air to allow a larger cam, so you don't mess up the EEC module . There are some cam manufacturers who advertise computer friendly grinds. Good for about 30 HP If they're friendly to computers, how much different than stock can they be? Heads will at best get you 25 HP, Intake, maybe another 20. By this time you've just sunk $2500 into your engine, but you won't get the horsepower increase, because you now need a better throttle body, and larger injectors to take advantage of the bolt-ons.There's another $400. Now you have to consider the reliability of your system, since it's probably a daily driver. Take it from me, if you like to continually tweak your engine for the varying weather conditions, do the mods. Or...save yourself alot of grief, and some cash. Supercharge. Get a 40% improvement in power, save the reliability hassles, and all the rebuild trouble on your engine.
