John,
It's true that the bearings are larger, but the later (FH type) engines are
considerably less robust than the MKIII FD type. The FD is generally considered
the best of all stock 1300 Triumph engines - a strong bottom end without the
drag of the larger bearings, together with a decent cam profile. If it's
running well I've nothing against the FH, but if I had a choice which engine I
was going to spend money then the FD would win every time.
Cheers,
Bill.
