Many people on here will be very happy with stock or near stock or performer (not-rpm). If I go alum on my F100 its the performer... I wanted that engine to be a killer from 1800 to 4500. and with these FE's when you tune for that, man they can deliver. I have so much fun with my truck, and i do not ever have to shift if i do not want to. People forget a strong FE should smoke the tires in big block style at 1500 - 2K if you want... forget that big stall stuff. and even better get a small solid cam to really ad more hit to the power at 2K rpm. With my engine I imagin i am at 450+ torque at 2K, far out torquing Jays Dyno mule, but I only have about 325 HP, ot 410 hp. But for my truck its great!
