P6 V8s (had one myself) for the UK market were 135-141 BHP, depending upon exact spec (the auto had slightly milder cam profile so the cha ges under power werent too aggressive) and year. The motor was upped to 155ish for the introduction of the Leyland era SD1.
In the grand scheme it actually wasn't all that as a performer, but back in '71 when mine was made the average family car did around 50 horses so relatively speaking it probably seemed like it was powered by nuclear fusion.
Maybe it was something else with the V8 engine in it!!
Or maybe it was my simitar V6!
