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.
