First off, now we know 318s will run, lol. Secondly, I believe ma mopar absolutely new what they were doing with those numbers. First off they manipulated ratings for the cars, say 69 and older for racing purposes. Then they manipulated rating for cars 70 or newer for insurance purposes. Insurance was a real killer back then. The car prices were out of reach for most kids and if insurance companies saw 300 hp ratings and if you were under 25 years old you were doomed. Hence the beginning of the lower hp ratings, again. And guess what, they're doing it again. Everyone wants the highest hp ratings again. And the factories are obliging.
