Connecting rods
Chrysler small block connecting rods are essentially all the same. And, Mopar connecting rods do have a good bit of integrity. All are forged, but the 340 rods (p/n 2899495) are bigger and stronger than their 273/318 counterparts (p/n 2406785). Both part numbers have full-floating wrist pins. The 360 four-barrel rod (p/n 3751015) is also a heavy duty forging, but has a pressed pin. All small block rods have a 6.123" center-to-center length, but 1974 and later 318 and 360 rods are of the pressed pin design.
