OT max economy, engine stress

[Todd....!!]

In regards to the Statement about "Nearly WOT at low rpm is the key to
good economy.....load the rods and pistons though because their inertia
cannot offset the gas"

If what you say is true, then wouldn't lightweight aluminum or alloy
connecting rods as well as lightweight alloy pistons and pins help to
offset the inertia prob you are referring to?
