what were you running for oil..looks like mud...and by the looks of the timing chain that motor had a few miles on it.
a motor is a motor, it don't mater what it is you have to take care of it.
ps how can it be all stock and have a forged rotating assembly ???? that is just a stock motor by the looks of it.

I thought that the rods were also, but i didn't know that they all had them, thats cool.
but, you still got to beat on it pretty hard to tear up a forged rotating assembly, stock or not

thats the type of material they use to make them....the 4140 and 4340 rods are much stronger them stock rods.

In 302 rods, the C8OE's are good to 7500 rpms with ARP bolts. Beware of the 90's rod, I think the forging numbers are F1TE, I've seen a couple of stock applications that broke these. Some of the stock forgings are better than others. Others to stay away from are the old 352/360 FE rods, lay one next to a 390 rod and you'll see the difference.
