318 connecting rods

Also when you combine the lighter Pistons that are pretty much commonplace now it drastically reduces the load on the connecting rod. I did a thread about a year ago rod breakers wanted which confirmed my belief that very few I mean very few HD 340 rods or small block Mopar rods at all broke from normal abuse. Almost all were due to other catastrophic failures of the motor which put excessive load on the rod causing it to fail. I've run HD 340 rods for 40 years and never had a failure with many RPM sweeps over 8000 RPMs due to miss shifts . But that being said new quality rods are always a great piece of mind if you're going through your motor.With top quality rod bolts being a must because they are definitely the weak point.
