Ok, here's the situation...

I have oil pressure problems with my 951 so I can't start it. It's getting pretty cold here (under 0 degrees Celcius) and I'm not 100% sure of my coolant mixing... I want to get everything out of there ASAP to avoid cracking the block.

Is there an easy way? With the drain plug out, the coolant remains in the block yet?

There are two drain plugs, one in the radiator and one on the block. Maker sure that you remove both. Also, you might try a wet/dry vac to vacuum out any remaining coolant.

Is there any pic showing the block drain plug? Thanks, it's appreciated.

It's a 13mm bolt at the rear of the block below cylinder #4 exhaust header port. It's hard to see, but you can feel for it and remove from underneath.

Yeah, there is a recess in the block that it sits in, underneath the #4 heater, tricky to find, often stuck in there really badly. However, if you remove that, loosen the coolant bleed screw, and pull the rad drain plug, it will be about 99% empty.
Anything you pour in will mix with the tiny bit that is left ,and you should be fine. Re-fill it like it is empty. Keep in mind, it will be very difficult to bleed the cooling system if it will not run, but on the same hand, what does it matter, it can't overheat if it doesn't run
