Those millions of chevies also made no power or compression per cylinder to speak of
Edit: looks like the rod in the picture above already has a squirt hole where the neck begins, 12 o'clock.
The stock oiling system supported 105hp in the powerglide cars of '50 thru '52. California Bill Fisher's speed manual and dyno testing was all done with the stock oiling system delivering 125 to 150 HP depending on the mods.
The pin oiler hole is part of the stock system. Some shade tree guys would peen the hole over thinking it would raise the oil pressure . . . only to starve the pins . . . :-(
