P6 was about 135 (I had one), SD1 about 155 in cooking trim with carbs.

I don't know why the engine was derated for the stage 1, but it assuredly was...

IIRC it was a big drop in compression ratio and smaller Stromberg carbs instead of SUs. Possibly done to make it more tolerant of lower quality fuel when used abroad, but that's just a guess.

Plus, iirc it would have better/more usable torque, with less power, or perhaps that's just nonsense that has stuck in my mind

I'm not sure about more torque but it would probably be less peaky and, as you say, more useable. The Rover V8 was never an ideal engine for this sort of vehicle, at least not an everyday one used by grownups.

To cope with lower grade fuel, plus a lower compression ratio
There were also airflow restrictors in place

Even with the introduction of the ‘One-Ten’ & front discs, it was still restricted to 114BHP
Later models, like my old ‘E plated’ 90CSW-V8 had SU carbs & 134BHP

EDIT @ 18:20
There's a feature about the low performance of a Stage 1, in the present issue of https://www.landrovermonthly.co.uk, but my copy's in my locker at work, & I'm on annual-leave till 5th March
