Mopar 318 Connecting Rods

The Mopar 318 had 2 styles of connecting rods over the years. Until 1973, the 318 used a light weight forging with full floating wrist pins that was similar to the connecting rod used in the Mopar 273. In 1973, Chrysler changed the 318 connecting rod to a stronger, heavier rod with pressed pins, very similar to the rod used in the Mopar 360. Normally it is considered good practice to replace a weaker connecting rod with a stronger one. In some cases though I would advocate going the opposite way. The early 318 rod is made of good material, and while I wouldn't used them in a high rpm screamer, the lighter weight would be welcome in a mild to moderate build. I would have them rebuilt with stronger rod bolts from ARP or Pioneer though. Other then that, they should be fine.
