Ford 460 engine questions/issues

In my early mechanical years, I painfully learned I did not know and it was too costly to learn the hard way about how to rebuild an engine so as to mimic exactly the performance and longevity of a new car engine. So did 90% of the rebuilt engines I bought. They leaked and burned oil. High volume oil pumps are a farce. I learned for racing only a high volume HIGH-PRESSURE oil pump does a damned thing different than a standard oil pump. The camshaft grinds provided less power on more gasoline. I purchased a fuel saver grind of CRANE cam which provided far less power on the same MPG. All the misfit engines burned far more oil and delivered far fewer horsepower.
I was introduced to factory OEM replacement transmissions. GM Mr. Goodwrench trannys came with improved valve bodies with far less porosity that caused longevity issues. Double hardened gearsets and redesigned reaction shafts for the torque converter. You'll get this is a standard shop rebuilt tranny? Keep dreaming.

Factory rebuilt alternators impressed me and that ain't something trivial. I re-tested rectifiers to MY standards and never found a bad one. They resued only original rotors and stators. Raised my eyebrows.

But to simply slap bearings and rings into an engine is a recipe for disappointment. The extra fuel and oil to be consumed make this choice a real loser in my book.
