Interesting. Both commission and engine numbers you give would make this
an early 1972 model, NOT a 1971. Restoring power shouldn't be much more
than raising the compression ratio, then maybe monkeying with carb needles
or settings and perhaps some distributor work and different pistons.
The U.S. 1972s and later had this low-compression engine with the dreaded
"recessed" block, so it's likely that decking the block and milling the
head some amount (can't help you on specifics -- anyone else care to?)
would be a good start to restoring the power.
FWIW, I had a 1972 in Laurel Green -- KF10224L -- now owned by another
sometimes Triumph lister person. The engine isn't really all that bad as
is, but it sure can't hurt to bring it back closer to UK specs!
