As a point of reference, I have a '51 Mercury engine in my '51 Ford club coupe; it has massaged Edmunds heads, a Mallory dual point, and a 2G on a bored out Merc manifold. It also has 3.55 rear end gears and 2.25/75R15 rear tires; no overdrive (which I intend to remedy). It cruises nicely at 65 mph, turning 2800 RPM. Anything over that is "uncomfortable"; the engine seems to be in a range it doesn't like. Don't get me wrong;, it will easily turn over 4000 RPM, but if you want to just ride down he road, 2700-2800 RPM is all these negines like.
