Any B series would most likely fit easily. MGB would be the most likely place to find one.,,an early 70's 1.8 would be just right
Any BMC A series will fit exactly as well from:
Morris minors, A-H sprites MG Midgets etc. I am sure that the 1275cc Midget engine at the end of run would be the easiest to find.
A triumph spitfire engine could be persuaded in there as well.
I am not sure that any cross flow engine would fit as the originals are all Exhaust and inlet on the same side ( passenger side in Canada)
In the UK you could probably get an B series for a dollar....here I'd get a copy of Hemmings.
Either engine is awesomely simple..... fill it with 20w-50 and hang an SU carb on the isde and you'll get 50 genuine british horsepower.
