Rods powdercast (not forged)
Crank cast-iron

When you cast a metal you have to heat it till it melts and then pour it into a cast and it becomes brittle after doing so because you changed the grain structure of the metal. Where as in forging you start with a blank and you stamp it with a press until the shape is formed. This imparts strength to the piece.

They don't break "easily" by any means...I've seen more than 430 rear wheel horsepower go through them for sustained periods of time. They are however typically the first thing that does break if you make too much power (450+), simply because it's hard for a crank, or pistons to "break"...so the rods do.

and the rods are forged also, not powder cast

most of the time when the break it is at a rod bolt

powder cast/cracked cap rods did not appare till the early '90s
