You know the thing I dread the most about all this is draining the radiator/block! Last summer when I had to replace the opti/WP when I pulled the WP even after draining rad and block antifreeze ran all over the garage floor, frame etc because some nasty antifreeze was hiding out there in the WP. I HATE antifreeze,it's nastier than oil, grease or dirt.
It's hard to get it all out. Having the front end jacked up helps a bit. And you can get more out by using your air compressor (set at 20psi or so). You can get enough seal on the radiator cap hole using just your hand with an air nozzle to blow more of the antifreeze out the drain.
It can also be done with your shopvac set to "blow" but, the vac needs to be empty, clean and it's best to remove the filter.
Sidenote: Flushing your LT1 block- the knock sensors need to be pulled, there's an amazing amount of crud behind them. But, it's a really messy job, for the driveway not the garage.
