A quick tech query for the 7000rpm boys -

I noticed new Pheonix & Hadley rods omit the angled oil relief holes in the top shell, and i wondered if this was because they were a non-useful feature, or was it because of the material property differences between babbit and modern shell bearings in relation to heat & oil flow/pressure, etc.

I'm using Hadley 1.5" rods in a splash-fed engine that will be raced. Is there a benefit to drilling them? Many thanks
Dirk
