I know it is not your question, and maybe I am cornfused, but check the knurling on the rear main seal area. No personal knowledge but have seen mention of "reverse" knurling and oil leaks? 
It takes gasoline to interest me.

It is indeed a right hand rotation engine and as you mentioned, the oil pump drive gear has backwards teeth.
I get the feeling that it is one of the industrial engines that turns the conventional direction but used a gear driven cam. Those cams were ground to run in the opposite direction of the crank.
The cam, cam drive, oil pump drive, oil pump, and distribtor are different. All other parts are conventional.
They can be dropped in a vehicle and used like any other engine. Just be sure to wire the distributor accordingly.

Seems to be some confusion on what is right and left hand rotation. Rotation is determined just like the left and right side of a car is.
Left - CCW, regular rotation, like in cars
Right - CW, backwards rotation, AKA reverse, common with Chrysler Marine engines.
The gear drive cam is not the same as a reverse rotation cam, only the rotation is the same, lobes are in different locations. The dist drive gear is the same. Also, a gear drive with a regular cam will not work in a reverse rotation motor.
Anyone that parts out a Marine or Industrial motor, save the cams, dist gears and cam gears. There aren't any new cam cores available, much less new dist drive and cam gears. People rebuilding Chrysler Marine motors need them.

The right hand "reverse" rotation motor does have the knurling backwards. The knurling cam be polished out and a neoprene rear seal used, but why with all the extra unused 440 cranks laying around from all the big stroke motors being built.

Understood.
I had the impression that the OP may have stated it incorrectly.
