I have a Mk 2 998 Cooper registered new in NZ in 1970
It has had a replacement motor, I do not know when it was replaced.
My question is how can I identify if it has the correct engine block for its year?
The replacement motor No 99H791P- original motor No 99H377CH
Do engines with electric fuel pumps have the mechanical pump blocked off with a plate or is the mechanical pump mounting unmachined, ie no opening in the block.
Are there other casting marks on the block that will indicate the approximate age?
Same question for the gearbox, it is a remote change 2G1128.
Any help appreciated
