G2 CRANK CASE OIL WAY

Can anyone tell me what this second oil way is that is connected to the usual oil way with a channel?
I have probed it with a piece of wire and it seems to end in a dead end about an inch deep.
I have several G2 crank cases but this is the only one with this modification.

Poke it clear. It's the later, modified oil feed to the camshaft lobes.

I think this crankcase is to be used with the later-type longer stroke CSR oil pump.

Thanks Clanger, very informative, I will give it a poke.

as opposed to my 350 or older 250's that just relied on oil sloshing around in the casing
