That is a great read for detail-nuts and gearheads, but it is in reality just a little on the propaganda side. Much selling of typical engineering of the day as "advanced" or unique to the motor, with the prose written with an inference that maybe Ford pioneered most of the technology.
Remember, Chevy really developed and brought to the masses the poly-angle valve technique with thier "porcupine" heads on the big block MK-IV engines in the early sixties.
Ford basically took that design, added thier own "improvements" and came out with the 385-series engines ( 429/460). Shortly thereafter, or maybe even concurrently Ford used much of this design technology when developing the mid-block sized "Cleveland" 335-series engines.
It is definitely a great design...far ahead of the older 390/428 designs, as well as the Windsor design.
Too bad the Cleveland, which was perfectly suited to take advantage of the horespower-crazed 60s customer was so ill-suited to survive in the emissions-saddled requirements of the 70s.
