I am running the Butler prepped high pressure pump in my 469. I have asked my machinist to drill and tap the front two tiny oil galley plugs but I wondered if there were any others I should get done in the process. I don’t want any popping out

IMO, all the oil gallery plugs should be tapped and threaded plugs (STEEL PLUGS) installed with Aviation Gasket Maker lacquer.

Besides the two threaded ones in the back and the two in the front, there are no other deadhead oil passage openings. I do suggest laying back the sharp edges in the drilled oil passages in the #1 main saddle, to let more oil get over to the passenger side.

Do they have to be steel plugs? Will brass work as well. And how about using one of the Silicon based sealers on the treads. Just thinking down the road trying to get them back out.
Thanks

Brass will work just as well and is much easier to drill an .030 hole in. Just use medium strength Loc-Tite.

Correct, brass is easier to drill than steel, but also keep in mind that there are soft steel and hardened steel plugs out there. The shiny steel ones in the kits are typically much softer than the black ones bought over the counter.

Even so drilling them with a .030" drill bit can be a lesson in humility. Right to start with how many shop drill presses have a chuck that will close tight enough to hold a .030" drill bit? Probably none of them. Second, it is much easier to drill a larger hole then "peen" it closed and re-size it to .030". Another option and what I typically do here is to drill a larger .100-.106" hole then tap it for a 6-32 brass set screw with a .030" hole drilled in it. Very easy to drill the tiny brass set screws vs drilling a big/thick NPT plug no matter what material it is made of.

I always drill the internal plug to spray the distributor gear and also one of the front plugs to spray the timing set. Some say the drilled front plug is over-kill, but there are no negatives anyplace from drilling it and I've never seen a timing set die an early death from having too much oil sprayed on to cool and lubricate it........Cliff

Are you running a 80 psi oil pump,or a 60 psi high volume pump?

[PunchT37]

Course, I've got a 455 here that has been together since 1985. It has the 80# pump with staked gallery plugs. The oil pressure gage wraps all the way around to the 0 peg when cold many times. It has swelled many oil filters. The gallery plugs are still there. Lucky, I guess.

The 80 PSI

[tom s]

As many have told you not necessary.Tom

[steve25]

Yes, it only makes for a greater power loss and hotter oil and more load on the Dizz gear and drive shaft!

That, it does.

Any machine shop quality press will handle that size and smaller, and any decent quality, and I stress decent, consumer drill press should do the same. As to decent quality my Harbor Freight 16 speed drill press I've had since '95 will tightly grip a #80 (0.0135") bit with no problem, and I've drilled a number of these plugs with ease.

Butler has the plug drilled for like 3 dollars

I can return the pump to advance and get the stock pump. One of the perks of working there for years in HS and part time while I’m college.

M54DS is that the part number I need?

You’re gonna return a Butler prepped oil pump at Advance Auto Parts?

If it’s gonna cause me distributor problems and cam gear wear then yes. Rather take a small lose than mess up a roller cam or a dual sync 465 dollar distributor
