From conversation elsewhere:
Man I remember back in 1982, we all thought we'd be driving nothing but 3-cylinder diesels by the turn of the millennium. If you went back and told some gearhead in my high school class that in 2017 Dodge would be selling a "street legal" 10-second Hemi Challenger, he'd think you were talking about the 0-60 time of a 4-cyl car.
The computer changed everything. Not only in engine tuning and performance, but in design and modeling.
I had an example of a classic late Dark Ages car, an '84 Trans Am with the LG4 305c.i. Rochester Quadrabog motor. A hunnert and fifty horsepower and nearly every engine function powered by enough dry-rotting vacuum tubing to reach to the moon and back...
Only a few years later and exotic computer-designed and controlled long-runner port fuel injection systems were common on domestic performance cars and HP numbers were on the right side of 200 for the first time in a decade.
It was coming out of an awful time. Like a friend wrote: When he went into seminary you could buy a Mustang with a nearly 400bhp engine option. When he left seminary, the Mustang was a Pinto.
Being a car enthusiast in America in the latter half of the 70s/first half of the '80s was like being a dirt farmer in Fifth Century Britain, marveling at the weed-grown roads and disused aqueducts left by a race of giants and building your pig shed with stones looted from a burned library.
