I would like to offer a different suggestion to lightening the TR-6 flywheel.
Use a GT-6 flywheel instead. An aluminum TR-6 flywheel (street) is about 12
lbs, GT-6 flywheel is about 18 lbs and TR-6 flywheel is about 28 lbs. I made
the mistake of buying an aluminum flywheel (Paeco - no,no,no!) for the TR-6
engine that I swapped in place of my GT-6 engine. I acquired the TR-6 engine
core before pulling the GT-6 engine. After looking at and weighing the TR-6
flywheel, I bought (ordered and waited months) the aluminum flywheel thinking
that the GT-6 would have a similar weighted flywheel. I was quite surprised -
and disappointed in spending $500 for a poorly machined aluminum flywheel - at
how light the GT-6 flywheel was in comparison to the TR-6 one. If going this
route the TR-6 rotating engine components / GT-6 flywheel should be balanced
when the TR-6 engine is being rebuilt. I saved my GT-6 flywheel (and the old
GT-6 crank - for the balance shop to use as a flywheel fixture) in order to be
able do this swap in the future.

Well, I can't help you regarding shaving weight off the flywheel (but am
interested in hearing the discussion myself, as I'm now at that point in my
restoration). However, I can offer my opinion with removing the flywheel.
I have my engine and transmission out of the car - and took them out prior
to my pulling the body off the frame. In retrospect, if I had pulled the
body first, pulling the flywheel with the engine in situ would have been
easy. However, with the body firmly attached, pulling the flywheel would be
a tough job for a home garage mechanic (in my opinion). Now I'm not saying
it can't be done, but wrestling the transmission out of the way, and then
getting at the flywheel would be tough.
If you are considering an engine rebuild, I would wait until then to do any
work to the flywheel.

Greetings Listers--
I'll be installing an OD tranny and clutch in my '76 next month and have
been considering having the flywheel shaved while I'm in there. I've
heard pros & cons about doing this from people I respect, but would
appreciate additional wisdom. I'm not looking for race-winning
performance with this somewhat tired engine, but would like to get a
little more low-cost punch out of it if possible. (Aluminum's probably
out of the question price-wise.) What's the verdict on safety? If I do
have any metal removed, I would probably stay on the conservative side,
but what's recommended and what can I expect in the way of performance?
Finally, since I've loaned out my Bentley manual and have forgotten all
that's involved in removing a flywheel (special tools or whatever), I may
put the decision off until I have the engine rebuilt in a year or two.
Thanks,
Ian
