Poly Engine what was good/bad about it and why is the LA better?

There are a few foibles in the novel, Dennis (narrator of the story) said "Like the 382's they used to put in those old cars. Like Christine.", & "He dropped the hydramatic into D". Also indicated 1 4bbl when They discovered the car, later "318 painted on the air cleaner" post "resto"...given that, I have an appreciation for Carpenter's crew, doing the movie Christine w/the top of the line '58 engine combo accurately.

King didn't know anything about Plymouth Furies, just thought "Fury" was a cool name for a monster car. So, he didn't know that the 56-58 Furies (is that the plural of Fury?) were each a special model, each available only in a special Fury color. I.e., no red 58 Furies (or 56 or 57). Also didn't know that ALL 57-58 Furies had two four barrel motors, whether 318 in 57, or 318 or 350 in 58. Later ones - all colors, and single two and four barrel motors. But not 58. Also, of course ALL 1958 Chrysler products with automatic transmissions had push button controls, not column shifters, and they weren't called Hydramatics (GM), and they didn't have push button inside door locks (you moved the inside door handle forward to lock it from the inside).

All those mistakes plus the number of 58 Plymouths that got wrecked in the making of the movie pretty much turned me off. Jeez, if you're gonna write a book whose main character is a 1958 Fury, then do some basic research about the car. But I know a lot of Mopar fans like the movie. Maybe because there are so few movies about Mopars?? (Vanishing Point??).
