Sorry, completely missed this.
It is down to the advance weights and springs, total advance stop, and probably the vacuum capsule in the distributor.
If you use a P6 or P5B distributor, which will be points, they are meant for 5 star fuel, so the advance curve is unsuitable for modern fuels, it advances too quickly. Causes pinking or pre ignition, and will blow holes in the pistons if you are unlucky.
Opposite with the LR low compression distributor.
If you use 9.35 pistons you can use a Range Rover distributor, and get away with it.
You could of course get the distributor reworked, but those who can do this properly are very few and far between (and expensive)
Thanks for the info, although I'm a ways off being able to make good use of it.
Getting a RRC dizzy would probably be the easiest way to do that if I am upgrading the pistons, but there would be a case for just switching to and aftermarket electronic ignition control, as it would be about the same amount of work (possibly less if the RRC part I can source needs rebuilding).
