wrist pin oil

What size wrist pin oil holes should I drill in my rods for floating pins?

are you going to drill it on top or bottom? I think a small one like 1/8 but probably isnt that critical. I have seen them on top, but read that the bottom drilled diagonally is better. cant confirm.

Thought about drilling in the top and from both sides at an angle from the bottom. Chebby guy told me that worked well on his.

According to the "hemi engines" manual [page 182], you can drill a 3/32" hole with a chamfer in the TOP of the rod when using floating pins. This is what I did.

me too (steel on steel floating). Not positive but iirc reading something about drilling the 2 holes at a 45 on the sides weakens the rod.
