It does no good unless you do the other mods.Mine was done at the machine shop and he did the other mods when it was done.That was about 12 years ago.He had a fixture made so that it was drilled right also as some of the castings are thin from the factory.Rocky

Is drilling and tapping the oil pickup boss to 1/2" still a common practice on street/strip 440's?
No It was and is a bandaid to help correct other things in the oiling system Get the bearing clearnances right, not to tight, get the pressures and flows correct and use the correct modern oils, not to thick You'll be golden Oil needs to flow to do what it is designed to do, lubricate and cool the contact surfaces on rotating and recriprecating (SP?) parts
At what performance level is an external pickup considered mandatory? What is the best external setup?

I do it because I can. It is one of those mods you either choose to do or not. To me it is part of getting the oil system up to a standard where I think it should be.
Take a look at any modern engine today. I have seen many very small displacement engines that have oil pickups the size of a hemi delivery system. Many of these modern systems use lower oil pressure, very light grades of oil, and likely many other things that I have not yet learned.
I now try to run lighter oils that return faster and lower pressures. I now believe that good solid oil volume is a must.
Just because others get away with sucking oil through a straw and have had no failures, doesn't mean you won't. I am certain most of the people who build engines that live, have come up with many ways to improve all the little things in their engine building practices.
I know most of these builders go through their engines and look them over more than I do. I am just saying that the old modification was done to one of my first builds almost 30 years ago and it still lives with the original build components.
I no longer run 40, or 20w50 weight oil like I did back then. I have evolved into different thinking, and I personally believe that some of these old school mods still have a place in engine building.
Too many cars, too many parts, too little coin, too little space to work in, too little time left to make it all happen!
Update: down to one ride, still too many parts, a little more jingle in the pocket, gaining space, and it's going to happen this year!

This is my opinion. Based on my experience I would look at the 1/2 pickup if my shift points exceed 6000 rpm. If your engine is a low rpm affair and does not exceed 6000 rpm I think a stock system with an attention to detail will live a long life. The reason the 1/2" pickup is so popular is the hemi's came with one. The rpm levels the hemi's max hp were produced made the larger pickup necessary especially when you consider the first two years of production the hemi was a strictly race application. When the engine was civilized for the street it retained the 1/2 pickup developed in its racing trim.
Getting old just means you were smarter than some and luckier than others.

The suction side of any hydraulic system benefits from a larger inlet.

ime, it's not needed. the last all out bracket engine i built had the 3/8" pickup, and is in a 'cuda that runs 9.60 all day long, with absolutely no issues. my personal car has an external pickup, because it HAD a 1/2 internal pickup, but the boss cracked during a freshen up. remember that the milodon 3/8 pickup has the same diameter tube as the 1/2, only the end is different.
for what is the good life if not doing things thoughtfully?

We have never done that mod to any of our 383 or 440 engines.Ran them up to 6800 with no problems at times.A good engine build,with proper bearing clearances,and good oil,will be all that is needed.

Any motor I build that will be shifted above 8000 RPM would have a good external oiling system on it, preferably a dry sump system My current low deck stroker (505 C.I. 400 block) bracket motor has a Milidon pump and dual line oiling system with the swinging pick up in the Charlie SS style fabricated aluminum oil pan, Charlie extended the dual line Milidon swinging pick up for that oil pan.I used it, the sytem, because I had all the parts hanging on the wall and on the shelfs It, this oiling system, has NOT given me any problems (like no oil pressure on start up after sitting for a while ) since the motor was built and dyno tuned three years ago Unlike some other dual line Milidon oiling systems I have used in the past
