What is the lightest Lycoming as used in an RV4,6,7,8?
Is it the narrow deck models?
Does the conical mount weigh less than the dynafocal ring?
Are some cylinders heavier than others (I mean parallel valve units).
Crankshafts, Hollow, solid, certain part#'s? (counterweighted would be heavier).
Looking for the lightest base engine, then add the lightest accessories.
Might consider O-360 over O-320 if it's close.
