An engine builder told me that if the reciprocating parts are within 10% of the originals they do not need to be rebalanced.

Ford is old time stemming from the days of the Model T.

Their internal engine parts are theoretically ready for the "proverbial farmer" to change on the tractor stuck out in the fields?

Pistons were always like that and many many engines had their pistons and rings changed without ever even seeing a hone and basically still run fine.

In fact, Mark Donohue in his book, "Unfair at any speed", remarks that in regards to the Camaro (Roger Penske's) that they had found the perfect condition of the short block just being "friendly enough" with it's parts, read that as on the loose side, and the heads being nice and tight and precise.

Considering the results, AND the source, I defer to the higher authority on that?
