Besides the 27 inchs? Or the bore and stroke of it?

The bore is smaller on the 198, thats it, same stroke I believe. I think it's the 170 with a smaller stroke.

The super six? Try this link below and scroll down looking to the left of the screen and select the engine family and /or size for a very good write up on it.
