Just dropping in to point out that billions of miles were put on production Fords and Chevies with the "WRONG" side view angles shown at the bottom of the above image. I'm referring, of course, to the once ubiquitous torque tube suspension.
Yes, there will be a very slight speed output variation with each revolution, but it's not the end of the world.
In the case of the Ramchargers' '49 Plymout C/A, every effort was made to make the crankshaft centerline and the pinion shaft centerline collinear. Can't recall the exact driveline angle, but with the valve covers pressed up against the underside of the hood, it was a bunch! http://www.racetec.cc/shope
