connecting rod question

If it were me, I'd shot peen the rods, install new high strength bolts and have them resized.

I'd also have the bottom end balanced. I've always read that mopar wasnt too great at the factory balancing their engines, basically its a matter of durability, smoothness and power which you get from balancing. Just remember that a 360 is externally balanced, there is balancing weight in the vibration damper, and the torque converter that needs to be considered when balancing the crank etc. Your machinist should know this if you go forward, give him the vib damper and inform him about the torque converter weights.
