Starters are specific to a bolt-on or a press-on flywheel.  Be careful,
since, if you have it wrong, you will burn out your starter.  Been there,
done that.  Rebuilt a smallmouth with a bolt-on flywheel, but fitted a
starter for the early car.  Expensive mistake.

Question:  were there different gear ratios on the ring gear?  Reason I ask,
while I had the OD tranny out, I replaced the flywheel with a freshly
machined one.  It had a somewhat better condition ring gear already bolted
on.  I don't know the year of production of the replacement flywheel.
Bolted the same starter back in, but when I try to start the engine, the
starter clicks and whirrs, but doesn't engage. Jumped it with a good
battery, seems to be a strong electrical current going in.  Engine turns
freely by hand even with the spark plugs still in.

Thoughts?

New Hampshire where in a two day period it went from minus 20 degrees to in
the 50's.  Gotta love New England!
