full floating wristpins vs. pressed wristpins

Reviving an old thread instead of starting a new one, as I have similar questions.
The 340 I'm doing has 3418645 con rods with bushings in small end. Is it feasible/worth it to drill oil hole on small end THRU the bushing?
How do you tell floating pins vs pressed pins? Pins I have are 2.998" long and 0.984" OD
Thanks!

Thanks Rob. Od rather revive an old thread vs starting a new one.
I would do this myself as I have access to good drill.presses. 3/16" size.hole?


Just make sure to knock down the burr that you "push through" on the back side when you drill the hole...
