Because of rotational thrust, there are other changes. So the cam would bear on the same thrust face as normal.
The distributor drive
gear, not the entire assembly. It would be like a mirror image of the standard gear.
The
water pump impeller.
Probably the
oil pump as well.
Firing order probably wouldn't be 1,8,4,3,6,5,7,2, I'm guessing, 1,2,7,5,6,3,4,8.
So more than I stated earlier, didn't really think in the amount of detail needed.
Ooops, delmarrey beat me to it. I'm going sailing anyway, later.
