Flywheel

[Richard Taylor <n196x@mindspring.com>]

Fellow FOTers,
I bought a junked TR-4A motor to rebuild into a street/race engine, ie 125
hp and dependable. The crank will come out tommorrow and it appears that it
will have to be turned.  Whilst at the machine shop. I need to have the
flywheel lightened.  Therein my question lies.  Are there specs for this
process?  If not, how about rumor or lore?  Not knowing even this, I'll
even settle for gossip.  Thanks
