Connecting Rods???

Are the connecting rods numbered so they have to go in the hole they are designated for or is a rod a rod. Also is there a front and back to a rod? Can a rod be put in backwards?

Whitey: 1996 F 250 XL CCLB 4X4 7.3 DI ZF5 (The Work Horse) Lots of power mods
Whitey Jr: AKA Jr 1982 F 150 CCLB 4X4 351W C6 (Jr Work Horse) respectable power, but not over the top
The Bronco: 1987 Bronco XLT 351W C6 (needs work) Lots of off road mods and plenty of power mods
The Dodge: 2006 Ram 2500 CCSB 4X4 5.9 HO Cummins (The reliable ride that cant keep an AC in itself) (5th AC go around almost complete)

Re: Connecting Rods???

From the factory, no. A rod is a rod, but standard practice for any machine shop involves stamping the rod and the cap with a number so that they get put back together in the same orientation. Reason is to preserve the roundness of the journal. Best practice is to stamp the number of the cylinder the rod came from although it would make little difference to use the rod and cap assembly in another spot providing all the machining was done correctly.
