Engine Priming
I have read quite a few threads on this and know that everyone says to use a high speed drill with the appropriate tool or bottom of an old distributor. I do not have a high speed drill and am wondering if an air ratchet is an acceptable replacement. Anyone ever use this method? thanks

You don't really need a "high speed" drill. what you DO need is one that's tough enough to run the oil pump. I use a 1/2 air drill, but I've got lots of air. (and before someone jumps on that-- mostly it IS hot air).
If you use an electric drill and don't have a 1/2" use an old drill- it'll smoke it. Your ar ratchet might work, but it won't spin fast enough to get much pressure.

I used a cordless drill set on torque setting, not higher speed setting. Don't forget to put an oil filter on before doing this, don't ask how I know this.....................but I do know this for a fact.

Whew - I would not use an impact wrench for this IMHO. A standard electric drill is fine - just recognize that you're taking some life out of it 
You're just looking to prime to get oil showing at the rockers - that's all you need.

Another tip, have someone hold the drill and priming tool while you rotate the engine slowly with a strap wrench or something similar. I usually prime until oil comes out, and I rotate a few times past that.

This is all I did and watch for pressure at the guage when priming.

I've used my DeWalt 18V cordless before,but a corded or air drill works better.You dont need high RPM,but you do need torque once the pump gets primed up so watch your knuckles!If you don't have a helper,just give the motor a quarter turn with a bar a few times so the oil gets to most of the passages.
