But not as slick as the old flathead engines that used only two single-lobed cams to operate all the valves. The front cam operates both intake and exhaust for the front cylinder, and the rear does the same for the rear cylinder. all gear driven and very compact.

Here's another slick cam drive setup for a V-twin; a single cam drives all four lifters and the pushrods are parallel:

I like the "master-and-slave" connecting rods (like a radial aircraft engine) too:

I like.

All it needs is a radiator.

I like it, without the radiator. Classic motorcycle engines should not have radiators. They have worked fine for over a century without them. What I specifically like about that engine is everything appears to be gear driven, no chains to break. As the owner of a bike with no less than 4 cam chains, I love the idea of a motor without any. I'm fairly sure that chain failure is what will eventually kill my motor.

And I have a Chevy truck with a small block that has an aftermarket geared cam drive. Fits right under the stock timing cover.

You can get a much more efficient engine with water cooling. High compression with 87 octane is an awesome thing.
