Re: Who knows about the Mk II motor? (re: Bill Thomas)
Spoke with Bill Thomas III today. Don't have the answer I'm looking for just yet, but he's got a wealth of information.
The Mark I-IV engine story can get somewhat confusing, but this is what I think it is:
Mk I: The motor in the Z11
Mk II: The Mystery Motor, which was a prototype of sorts to the Mk IV
Mk III: Never produced
Mk IV: The production BBC that came in 1965
