Can't imagine why a 3/8 wouldn't do the job unless it is just wore out. Good excuse to buy a good cordless tho ![](/ubbthreads/images/graemlins/laugh2.gif) . Something 18v or better. Kevin

I used to do it with a 3/8 had them smoking a few times lately been using a 1/2 drill it's just right! :-)
Yes you need a 1/2" drill imo. Milwaukee to answer your question on what brand imo. If you own it you will use for something other than priming motors. Got to have a 1/2" drill as you go through life. ![](/ubbthreads/images/graemlins/grin.gif)

Milwaukee, 1/2 variable speed gear reduced..(like a Mopar starter). It will prime it, for a long time... Dont forget to rotate the engine while priming to get both rockers/ heads lubed... And ...hold on tight ! and run in reverse.. ![](/ubbthreads/images/graemlins/Twocents.gif)

Just happen to have both of my Milwaukee 1/2" drills in the same place, don't happen often. Both drills easliy over 10 years old and the big one has honed many engines with a real sunnen hone which takes some big azz arms and a strong back. Then the drill get's so hot you can't can't hold it no more with heavy leather gloves on, many times and it still works like new. ![](http://i21.photobucket.com/albums/b260/challenger19711/After%208-12-12/SDC17356.jpg)

With it dot to dot (6/12 o'clock) #6 is on compression/with the timing marks at TDC I believe the pass head oils then back up 3/4 turn (270 deg) till #8 is firing (rotor under #8 cap terminal) & see if the dr head is oiling. Easier on you (& the drill) & wipes less goop off of the cam lobes

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.

Tim Taylor the tool man said we are supposed to use power tools, arrrggh. ![](/ubbthreads/images/graemlins/grin.gif)
I do agree it can be done by hand but that would be more like work! ![](/ubbthreads/images/graemlins/wave.gif)

It takes less than a minute to prime with a speed handle.

My dad had a couple of the aformentioned big 1/2 inch craftsman drills. It primed quite a few motors years back before finally passing.
I smoked my Dewalt 1/2 after priming 2 440s. Still works fine, but the batteries are toast.
Smoked my 1/2 Skil the other day on a sbc motor. The Skil doesnt have much umphh...

Same car, bone stock 346s, 9.5 comp, baby solid. 12.24@110.

ok, priming the pump i can understand. but i want to prime the engine. if it takes a good 1/2" drill to do this, then how can you possibly prime the engine by hand?
well, reasonably anyway. i'm sure it can be done, but it's probably better than a weeks workout at the gym!
