Neikon,
A little
oil is probably more normal than many want to admit. Even a new motor, built with looser tolerances than the new varieties, will burn some
oil.
The decision to rebuild is up to you but why if there's no immediate need.
That said I did engine work on my aluminum 427 Windsor a few times in 65,000 miles.
Replaced main & rod bearings looking for better
oil pressure. Tightened the clearances a bit, it helped a little.
Rebuilt after an exhaust valve let loose and broke off. New piston, new rings, new heads. A complete rebuild.
Rebuilt after the car was crashed (not me driving) and engine & oil system were compromised.
Enjoy your driving, sounds like a great car.
Jim
