I believe the counter rotation can be achieved with the gear box. I have seen BW Velvet Drives stamped RH or LH.

I agree with Packard8's comment earlier in this thread that different rotations can be achieved with a gearbox, but there seemed some doubt that the Packard Marine engines were actually built in either rotation. I just came across a data plate from one of Packard's IM-357 marine engines and you'll note it was, like the postwar IM-245 and 356 engines, available in either clockwise or counterclockwise rotation; pairs with counter-rotation were used on dual prop-shaft installations.

The unconventional firing order for right-hand rotation was also used on the 1st and 2nd Series Eight (1923-1926 automotive motors.


Very interesting. That must have been in the heyday financially when they could afford the resources to make counter-rotating engines with custom firing orders!

I suspect that by the time the V-8's were offered they were all aftermarket conversions of what were probably surplus engines. The one I have has a serial number of SP-087 on the boss next to the oil filler tube. I'm guessing the "SP" is Studebaker Packard?
