nobody ever removes the block drains,

Only knuckle-dragging hacks and driveway grease-monkeys fail to remove
block drains.
Except some cars no longer HAVE block drains. Just like some
automatic transmissions no longer have dipsticks and fill tubes.

An engine without a block drain does not need one: the engineers will have
designed the block to drain through the radiator. This is why I said "if
applicable" in my original reply. But the fact that the OP was only able to
re-install about half the reported capacity /strongly/ suggests that he has
left a lot of old coolant in the block.

If the OP's engine has a block drain (or two), then it is NOT sufficient to
simply "flush" the block by attempting to run the engine with plain water
through it, and it is an extremely BAD idea to run the engine with plain
water as the coolant. Running an engine with plain water can damage the
head gasket(s).

The correct approach is, with the engine *COLD* and *NOT RUNNING*, to drain
the rad AND block. With the drains open, run plain water through the block
and rad until the water runs clear, let it drain again, close the drains,
then re-fill using the correct procedure as per the factory instructions.
