Those pink rods were way better than the stockers. The green ones were the good small journal "fuelie" rods.

My understanding was the pink rods were selcted from the piles. I have some that were the rejects, and I wouldn't run them in a stock smog motor

Without knowing what they were rejected for I would not run them as-is either.
What if it was for major flaws detected by magnaflux??

Generally described by GM as in attached image from Chevy Power 9th edition -
"high quality production parts" - "ground surfaces between rod and cap" - "heat treated to higher hardness " - " magnaflux inspected to be sure they are free of flaws in critical areas"
I can attest to the parting face surface finish being MUCH better than the nasty torn and ragged surfaces on production rods then.
That kind of detail can make a big difference in keeping a bolted joint from embedding and losing preload.

I'm thinking they were shotpeened (not just glassbeaded) too, but if the entire bolt seat area of the rod was not done peening's remarkable fatigue strength improving benefit would be missing from the area that needs it the most.

The pink is some kind of paint, not the Magaflux residue as sometimes appears on the Internetz

Did they ever come in the flattop 300hp hydralic cammed 350s?
I have a motor that is that, but they let 3 of the cylinder flood with water..
I may pull the pan and look.
I use new eagle rods for cheap they are fre floating with bolts.

Still used today from many of my older friends that I actually started using it at the bar from time to time now lol

Lots of 9 second cars, second gear wheelies and 8500 rpm re cammed stock 460 ford pulling trucks around here too...

The "pink" rods were select cores, with the pin bores centered well. They were magnafluxed, shot peened and hardened to 38-42 on a Rockwell C scale. I have actually tested some, like 25 years ago, and they were indeed harder.

The splash of pink paint was the identifier. :)

I think only the higher tuned options got the pink rods, tufftrided crank, sassy cam, power oriented intake, better heads and forged pistons.
300 HP 350 was a basic passenger car motor, even when installed with a windage tray in a Corvette.

But, you never know 'till you look.

Used the "pink" rods in the early '70's. Back then we thought they were pretty good. Ran them in my dirt late model until I found out about Carillo rods. In the years I ran the pink rods I only managed to break one. Probably my bad because It was a tacky track and I went way deep on the gear. Oops!

Another thing that really made those factory hi perf engines were ductile main caps. Those things are tough as hell!! They are identified by casting number 2482N. Even some 400s and 327s got them. I have both here. You can tell by feel that they are different. They are often shot peened too.

Hi Cedar machine,

So, was there a nickname for ductile main caps back then that folks today would consider quaint and maybe even slightly offensive?

(real tech question - where do main caps usually break?)

I don't know if people really even knew about the ductile caps. I never heard of any fancy names for them... Probably "high strength alloy" or something I would guess.

I've seen main caps break straight up the middle, but in very rare cases of extreme detonation. Always, there was much other damage. I saw one break with a doorstop looking piece missing from the middle.
I do see the grey iron caps get "sprung" to the point where they are loose in the block. A ductile cap has much more resistance to this. I won't even reuse a cap that has been sprung. I will replace it with one from my selection of take off caps. 8 out of 10 times I can find one that will cut and hone right in with the rest without line boring.
