Why is one 340 connecting rod bronze color?

Well I dropped off four pistons and 12 rods at the engine shop Friday.

The four good pistons I have were on four recently reconditioned rods ( one night of racing) but I figured it sure wouldn't hurt to have those four rods rechecked for size and straightness after being involved in a 7,000 rpm explosion! Hopefully we'll have eight good rods in a few weeks.

Gary, the shop owner, didn't blink an eye at the three copper rods in the box... seen them before.

The pistons that were in this 383 are, as I suspected, made by Ross so the shop is having four replacements made. I have one more with a little 'nick' that I will keep for an emergency spare.

One step closer...
