Oh, no, I am well aware of the distinction...and this is precisely why I
am considering the 1300. My understaning is that the weight of the larger
big ends is largely responsible for the shorter lifespan and lower revs of
the post-1970 1300 and 1500 engines.
As far as I can tell, these engines were available in the Mark III's.
Does anybody know what the engine production numbers are for the small-end
machines? I suppose my decision would be heavily influenced by how
easily and cheaply I could come by one of these.
Regards,
Scott
