In case you missed Polyspheric's earlier post above.

Quote:
Rating connecting rods by HP and torque is completely a marketing trick.
What breaks rods is reciprocating weight times RPM as the piston passes through TDC on the intake stroke, and it would happen with the ignition off.

Also, what Poly left out, was duty cycles, miles/rpm over the rods lifetime. That's most likely a unknown. Are they at the end of their life cycle or somewhere in between.
