Duson hi
On further checking there is virtually nothing on this later lorry engine that is any use to me as spares for my car, the manifolds are completely different as the carburettor is on the same side as the exhaust due to the bores being bigger (5300 cc) leaving no room for the inlet tracts to go between the bores, the crankcase may be cast iron and not aluminium like mine, the crankshaft however could possibly be the same as the connecting rods as the stroke was the same.The clutch is a plate type so the flywheel is also different, my car has a cone clutch.Even the cylinder heads would not have fitted as Crossley had dispensed with the rubber water jacket seals which were fitted to my car and used the modern type gasket which seals both water and combustion chambers.
Thank you for thinking of me, greatly appreciated.
