Actually John, You should do both. Draining gets 99% of the water out and
refilling with a 50/50 antifreeze solution fights rust and scale. Pull the
big hose from the tstat housing and pour the mixture into the hose. That
will fill the engine. You need to take other hoses off to fill the
manifolds. I left the riser drains off to be able to tell when the manifold
was full. Then you need to push the water out of the oil cooler with
antifreeze or disconnect a hose to drain it. Do whichever is easier. There
may even be a drain plug down there now. 2 gallons mixed 50/50 is more than
enough to do a V8.

Jim, for some silly reason I've thought the anti-freeze route was the way
to go. I've been afraid that draining the block through the drain plugs
and
draining the manifolds through their drain plugs was more dangerous than
putting in anti-freeze - that a little water may be left behind to cause
serious damage. I'd *love* to learn that I've been wasting money all these
years!
