Had one for a while. LOved it ,hated it!! Recammed it but 3 bearing crank meant i darent rev it!!
Half shafts were splinned but no matter how the were lubed thy would still lock up under load on a bend and then release so you were a yard away from line 
The 2500 Triumph straight six was an ancient long stroke lump that didn't like to rev much. Mine was pretty breathless above 4500 RPM.
Probably designed in the fifties. Plenty of low speed torque though. 
The needles fitted to the HS6 SU's had a lot to do with the 'breathlessness' at higher revs. BL were jumping on the bandwagon of emmission awareness at this time. The standard BDB needles delivered quite a weak mixture at the upper end, but a change of needles to BPZ or BDM needles enriches the fuel delivery at higher revs, keeping the same idling and low rev mixture, whilst not particularly adversely affecting fuel consumption. It has increased the driving experience, with a noticeable difference in pulling power at higher revs.
