More Cooling Questions - a load of hot air ?

Dear Collective
Who'd have thought draining, flushing & refilling would be so difficult ? Having now obtained some sealant & thermostat gaskets I applied them and so to refill the system - add the flushing agent - run the engine - drain it all down again - hose flush it again - coolant refill - job's a good'un.
Immediately hit problem with 1st refilling. The Manual says a capacity of 7.9Litres. Car is Sprint with original small rad albeit with a 3-core.
I filled it up to 4 litres, squeezing hoses as I went.......Could I get any more in ? Could I b****x. Front of car jacked up RHS by over half a foot - still no luck.
So I am assuming a huge air lock between heater & block.
BUT
out of curiosity, I re-measured what I had drained. It came to about 4 litres.......
SO
1) Are the capacities different to the manual ?
2) If not, where is the water that should have drained out trapped ? I can understand an air lock - but when I flushed with a hose water was running freely - and clear - from the outlets.
Flushing was undertaken by a hose through top rad connection; revers flush thru bottom rad connection; bottom heater connection through block; top heater connection through heater hose from thermostat housing; also through thermostat housing back through block.
All comments gratefully received.
