Re: Flywheel
Having the flywheel lightened is a debatable call, and is up to the individual. A few years back when many Borg Warner overdrives were installed it was said that a lightened flywheel would allow the overdrive gears to engage quicker. My personal opinion is to leave it the way Henry designed it.
You should have the flywheel balanced while mated to the pressure plate and then marked. If you are going to have the clutch surface machined have the shop also take material off where the the pressure plate mounts. The factory dimension is 1.123". The measurement should be restored anytime the flywheel is machined. The balancing should be done after any machining or other work is done to the flywheel.
Since you are going to be replacing the starter ring it is a good idea to have it "pinned". This will keep it from walking forward as some reproductions are prone to do. It is usually pinned in three places equal distance apart. The ring should be mounted on the flywheel such that the angled teeth face aft. You need to point that out to any machine shop you take it to as they are liable to install it backwards.
You can have this done at Jim's Automotive Services in Costa Mesa, CA 714-546-2969. Jim, the owner, is a Model A person. He can also supply you with a flywheel modified for a V8 clutch, as well as the V8 clutch and have it all balanced, if that is your desire.
