Here goes Paul pictures may help the 350Q had its flywheel moved to the front of the engine along with the distributor drive I do not think the motor was turned around and the cylinders renumbered, but that is possible I guess. Too many other things are in the right place to me for the motor just to be turned around and mounted backwards but here you go.
bare block flywheel at rt side in pic
here you can see the crank and flywheel etc assembly
Now this is the business end of the motor where the transmission hooks up
and here is the motor fully assembled see it looks normal when you can't see the distributor if you look in this pic you can see why Chris Craft did what they did. The motor was designed flywheel forward for clearance purposes in my boat they are mounted at an angle downward to the trans. That is also why the intake manifolds are so hard to find. You can see how the carb is tilted forward in the pic it is level when mounted.
