Really pretty interesting, all the variations in gaskets and such. Makes me wonder how we got so lucky building motors back when I was a kid, just slapped crap together with very little calculation and most of it ran pretty darn good. I guess the gas was a little better back then and the parts selection wasn't as broad which made not mismatching stuff as easy.
And we were DARNED happy with 350/350 HP/TQ, and weren't pushing 400-500-600 HP all the time. A true 350/350 would make you "king-of-the-street" in most locales...and will bring all sorts of grins and satisfaction to most people even today.
