No need for a drill, just use a speed wrench and turn it by hand. You only need to spin the wrench a few times to build up the oil pressure.
 It takes less than a minute to prime with a speed handle.
Not sure either why 1/2" is needed. I've done it many times with a plain 'ole $60 3/8" Dewalt. Yeah, it gets warm, but by that time the job is done anyway.
Parts I seek:
driver doorpanel, 65 Sport Fury, prefer black, needs to be 7-8 on 10 scale, might buy set
16" x 6" Dodge truck wheel(s), from early 70s?, takes 9" dogdish - need for a research job so cheaper is better.
69-73 C-body caliper brackets and/or splashields
Send a PM.

wow, this has been an eye opener! my 3/8" drill is old, and while i may give it a try, i'm going to bail as soon as it shows any signs of not liking it. it's a perfect little drill for 90% of what i need to do, so i don't need to ruin it or send it on it's way to ruination just to prime one engine. i'm also going to give it a shot by hand and see how that goes. from the sounds of it, i won't need the 1/2", although as posted earlier, hard to get through life without a good 1/2"

If you can would you note (& post) the 2 points where it oils

i assume you mean where it oils the rocker shafts? my #4 cam journal is grooved, so it should provide constant oil, even if a small amount.

In that case yes you'll have full time oiling

may need to start another thread, but here goes.
only had 3 qts of oil, but wanted to check out priming it by hand or with the 3/8". tried for a while by hand, (yes, counter-clockwise), and didn't get anything. tried the 3/8", and it grabbed pretty quickly, but then let off and was turning fairly easily. i could hear what sounded like air being sucked up into the pickup. even though the filter was not primed, i still thought that 3 qts would be enough.
so i put a 4th qt in, and that seemed to do it. now the drill is turning pretty slow, it's an old drill, and not much torque there. the engine was at TDC on the #1 cylinder, and i started to get a good amount of oil at the passenger side exhaust rockers, but that's it. i moved the crank around a bit to where it thought it might line up the hole for the driver side, but didn't get anything there at all.
so what now? try with a stronger drill? i would definitely like to see oil on the other side before i button this thing up. i know the passages in the block and head are clear, i spent a lot of time with brushes cleaning everything out when i did the block.
is it just because i don't have enough power on the drill? i was thinking that even though the cam is grooved, if the hole was lined up for the pass side, that might have filled that side up, path of least resistance. now that it's full, it doesn't take much to push what's there out.
anyway, any suggestions on making sure i have oil on the other side?

Keep it all in the same thread! Dont button it up till you get the other side squared away. with full time oiling there's no reason both sides shouldn't be recieving oil. I'd continue to prime it & if need be take off the rocker assy & see if the pedestal has psi (as you know cover it with something). I'm assuming the cam is gooped and the intake is on so you wouldn't want to do alot of hand turning which you shouln't need anyhow. I'd continue to drill prime it & maybe toss in another qt (can drain the qt before firing to get the level right) & if the drill has enough oats to prime one side then it's enough for the other side.
it's a roller cam, so no issue there.
i'll do all that this weekend and post back. thanks!
