It's great to get so much feedback on this thread, I've always perfered to drain the oil through the drain plug. I've even gone as far as using the engine's own oil pump to pump the oil out. I had a blown big block chevy in a jet boat that I used this method with. The drain plug on the oil pan was so close to the floor it could not be removed with out lifting the engine. So what I would do is remove the oil cooler line on the outlet side, start the engine and let the oil pump do all the work. I know using this method would sound a little scary to some people, and yes It dosen't get all the oil out of the pan, but it worked pretty good for me. After every summer I would pull the motor and inspect the bearings, and after changing the oil this way about 2-3 times a summer, running 16lbs of boost, 850hp, the bearings looked perfect. I ran the same main and rod bearings for 5 years.But I guess if there's a will there's a way.
