Like Barry suggested a hose to a shop vac. I suggest trying to snake a small hose, like 1/4", 5/16 or 3/8 fuel line in through the head, down into the block once you take the intake off, of course at the rear of the head as the head gasket is open there for coolant flow. Some help might be to bend a coat hanger (or stiff rod) to fit into the bottom of the water jacket, then thread the hose over it and then insert into the coolant passage, once in, hold the hose and remove the coat hanger or cut both to length. Removing the bottom water pump bolt on the passenger side will almost drain that side of the block to lower than the holes in the deck (jack that side of the car up??
) Otherwise its try to get to the block drains (long extension, with a universal snaked through the headers, steering etc) and hope they will come out

Add: As Doug suggested, take off the water pump and vacuum out the coolant from the front of the block. Its just another 4 bolts, alternator, fan and 2 more hoses, minimum, more fun with AC and PS bolted to the front.
