A good friend of mine had a machine shop. I'd hang out nights and weekends assembling engines, etc. We were doing a 390 for a guy, and he had his little boy, probably 8 years old, with him. The guy was asking about the different series Ford engines, and asks what does FE stand for, and without hesitation the little guy says, "Fast Engine!". We laughed our azzes off.
It's imperative that this stuff gets passed on!
