1967 273 Commando Connecting Rods

hi, if you install eagles SIR rods, you have to rebalance the crank, as they are 120 gms lighter each! this is not a cheap way to go! resizing and bolts is way cheaper. he seems a bit high on his labor though. the 273 rod is more than enough rod for a 273 motor. I ran a 273 stocker years ago, turned it 7000 rpm without any problems. the material is very good in the rod. just food for thought.
