Interesting period propaganda.
I like the part about even valve seat temperatures and less wear with no proof given. There's an obvious temperature gradient involved regardless.
50K miles pretty much the industry design life expectation of the day. Less driving.
They sold tetraethyl lead on it's ability to minimize valve wear, and as far as I can tell that was often repeated, but never proven. Beyond octane boost, it did lead to fouled plugs and the obvious environmental impact. The "solution" was metallurgical, hardened valve seats, etc.
The "straighties" v the "V"s. There's obvious geometric induced issues with inline. The V not without problems, concentrates the heat, etc.. Today this is designed with sophisticated fluid dynamic software. The days of empirical design are pretty much gone. Marketing hasn't changed as much. The triumph of plausibility over probability for the masses. The search for horsepower and customers is relentless.
