Cross drilling a crankshaft would be a hole straight through each main journal. If not, it's not cross drilled. I didn't think it would be.

Some later L88 crankshafts were cross drilled but GM decided that wasn't such a hot idea after all.

I'll look in an old GM listing to see if a code "P" is shown. I don't have truck codes though. I bet John Hinckley is correct (post #2) that it's a truck code.

Then am I mistaken about the discolored nitrided treatment too? I know its steel forged, that's pretty much unmistakable(I think)

I had a friend once showed me a book, probably 6 or 7 inches thick, must have weighed 10 pounds. He said it had every code number chevy ever had in it. Does the lime book cover all that?

All forged crankshafts have to have the journals hardened after grinding. Not necessary on cast cranks.

I keep telling myself that I will resume printing one day, but that day never seems to come.

Stay tuned...I have another idea.
What is the lemon book, if I may ask?

I don't know why you don't want to listen to John's answer. The engine was indeed installed in a Series 6000 truck. It was called a Taskmaster. That information comes from an August '57 TSB with full descriptions of '58 unit serial numbers.

That same motor with the same engine code can be found in half a dozen other vehicles in the same year. In just trying to get a confirmed answer on p suffixfor that year

The P engine code was used as follows:

1957-1961, 283, 160hp, 2bbl, manual trans, in a truck.
