Yes, I'm aware sleeves are or were available for these engines as shown
in factory and vendor spare parts catalogues. And I can't say for sure
either way that the engine originally inquired about has sleeves.
But are you saying that all these Spitfire, GT6 and TR6 engines from 1972
on -- "UE" low compression engines for the U.S. -- were, in fact, sleeved
new from the factory? I was always given to understand that there was
simply an additional recess at the top of the bore, for reasons I never
fully understood. But why would the blocks have been sleeved from new?
It's not as if they were aluminum castings and needed a harder cylinder
wall. (No Chevy Vega jokes, please.)
Anyone else care to jump in here with the documentation that I can't seem to
lay my hands on tonight? (All I can find are references to different head
gasket part numbers for the lower compression engines beginning in 1972.)
