There are a few differences. Do you know the engine type? (UB? USHM? 2, 3?)

Morris 8's had a different piston (less rings and a slightly lower compression)
Depending on the engine type it may not have an oil filter
Depending on the engine type it may have a different head (affects dynamo mounting and thermostat or lack of, also the radiator hose will need to be a bit different)

"The car was powered by a Morris UB series 918 cc four-cylinder side-valve engine with three bearing crankshaft and single SU carburettor with maximum power of 23.5 bhp (17.5 kW)."

"USHM series, getting a new cylinder head, still side-valve however, the unit being very similar to those used in Series 1 and 2 cars. Increased power to 29 bhp (22 kW) was now available and the crankshaft was counterbalanced and fitted with shell-type bearings"

It will be similar enough to use if you need it

Is there a way to identify the engine?

The water outlet on the head being vertical is the easiest way but the block has the oil filler tube further forward compared to the Minor engine.

The flywheel's different too, in the tooth count.

Also look for a circular brass tag on the side of the engine, down near the oil filler pipe
