I've got a 73 Mk I with stock 4-speed. I've also got a spare "low mileage" 74 engine that came with it. I know nothing of the car the 74 came from and have no idea if it was mated with a 4 or 5-speed. My question is, would there be any differences on the engine if it was originally mated with a 4 vs. 5-speed that could complicate an engine swap? I don't see why there would be but thought I would check as the rule for these cars seems to be expect the unexpected. Eventually the plan is to do maintenance on the 74 (adjust valves, replace gaskets/seals, timing belt, etc.) and then swap engines.

You need to check the engine # on the 74. If the number is below 2500 (give or take) they are identical, otherwise it's a later engine with a number of differences ( no rope seal, no oil separator, etc)

There are no differences, that I can recall, between the engines used for the later 4 speed and 5 speed transmissions that would impact your engine swap. Jim
