Hi Chris. On the last set of shells I bought, only the mains had oil distribution grooves. The BE shells were solid - no grooves, no oil holes.
TBH, I honestly can't recall for certain if previous BE shells have had grooves...but pretty certain not. Just the mains. I know Alfa dropped the hole in the conrod, and the hole in the BE shell over a period of time.
Found a piccy that (just) shows the main shell oil groove, and no hole or groove in a BE shell. These are shells direct from Alfa, rather than aftermarket types, so I guess there could well be variations??
