There will be a small amount of oil trapped inside the engine and cam chest, but nothing you can actually drain off, as it will still be there if you change oil and filter. So there is no benefit to draining the oil IMHO. If you want your modified engine to start it's 'new' life on fresh oil you can wait until you are ready to fire it up again before doing that.

Not necessary. If the oil is good, leave it and change at the next interval. No break in issues that leave metallic particles from a cam swap. If it's old now, I'd wait until after you got it running after the swap. I think I ran mine another 1000 after my cam swap. Having said that, make sure your work environment and hands are clean while working.

Ya should always store it with clean oil in it. Oil is cheap. Get it warm and drain. Put some dyno oil with filter in after swap. Run it a few miles (200-500). Swap in whatever ya run, with a filter. That will flush what ever ya got in there when it was apart.

Edit: some oil is cheap. Redline is not. Not starting an oil thread. Just sayin'
