Very little progress this week I'm afraid due to a 4-day migraine and now a stiff neck
Managed a couple of hours tonight so reattached the engine and gearbox and filled them with oil.
8 litres of oil came out, 8.5 went back in through the oil cooler return line. This should give plenty for startup and to re-fill the cooler and torque converter, then it'll drain to level once up to temperature.
A German friend told me about Mannol AG52 - approved to Audi spec for the 5HP, and £3 a litre instead of £13! I put this in Big Red and she's shifting better than ever so I'm now buying it in 20 litre drums.
Note: order it from German ebay. The two ebay sellers in the UK are the same bunch of lying shysters, and thats really the only source here. Its cheaper from Germany and arrives faster too.
Lash-up for spinning the engine on the starter and building oil pressure
Vid of the engine spinning over and triggering the oil pressure switch:

Put the spark plugs in, coil packs on, and coolant hoses back on
