Congrats on the new boat and welcome!
You are getting all the right answers. Simple way to tell a GM from a Ford is the where the distributor is located. The Ford will have the dist in the front of the engine and the GM dist will be at the rear.
Pictures are big on this site. Makes getting accurate answers much easier.
