4" Crank in 318 or 360 - Stock Reconditioned Rods Okay?

The old iron was cast with lots of nickle and other expensive/toxic alloys. I know China could care less about harming the environment but if they can save a few penny's on each part I'm sure they try to.

Yeah some of this is 40 years old now but if you can find the rods from a low compression 340 which looks not to been modify much, likely those rods had an easy life.

Some of the good stuff got beat up in the late 70's by the low octane gas, maybe one piston cracked and some how the rods got used again in other motor. Then years later, bang one of those rods breaks under load. So now China $99 rods are "better"
