Balancing question!

If you intend to take the rebuilt engine beyond its designed max rpm, like
say in a PP or BP that will see 9 or 10K rpms, you need to have it balanced
to make sure its good up to the new rev limit. Theres other mods needed as
well like pinned and hardened stationary gears, oil mods on the eshaft,
extra dowel pins between housings and plates etc.

Also if your mix/matching some rotating assembly parts you may need it
rebalanced as well.

Normally the rotating assemblys are good to 8K rpm in a stock engine I think.
