Jim,

Ref: Maintenance Manual X-7525 / Section 6A / Page 6A/58 CAMSHAFT BEARINGS / Figure 65 / Camshaft and Oil Gallery Plugs

The left hand rear oil gallery plug is not shown. It is a threaded plug in the end of the left gallery just rearward of the
distributor. A small hole is provided in the plug for distributor lubrication. The cup plug shown provides access to the threaded
plug.

Ref: Parts book 78Z / Section 8 Engine / Page 8-2 CYLINDER BLOCK, CRANKSHAFT, OIL PAN

Page 8-4 / Key 31 - Qty - 1 / P/N - 588927 / Description - PLUG, camshaft rear bearing

Page 8-4 / Key 32 / Qty - 2 / P/N - None listed / Description - PLUG-oil passage (RH & LH)

Observations / Comments:

The MM notes; "A small hole is provided in the plug for distributor lubrication." Yet the PB does not provide a part number for
either of the plugs which IIRC means "local purchase." That is strange since they MM does not provide the diameter of that hole.

Things that make you go Hmmmmm?

PS - I checked MM X-7625 and found NADA, however, in MM X-7725 on page 6A-80 the same info noted in X-7725 is provided.

Original motors we have opened up do not have this hole.� This is why after much thought about it we are not doing it.� I feel it's
a hi performance option those hi rev boyd so-- that's not for us.� I want a rock solid hunk of metal that runs on regular gas, can
accept any oil and produces it's best performance under 3000rpm.� No chrome, original valve covers, and all other visible parts.�
Needs to fire every time and have Bubba & Scooter be able to work on it.� With or without the hole makes little difference, if GM
felt it needed to be there, they would have done it even on Chevys!
