Yep it's all techy
Whether you believe it or not, it's fact.
The chorific ratio is lower than that of petrol
Very true. Another disadvantage of LPG is that it burns slower than petrol, so the spark has to be significantly advanced to get total burn in the cylinder. The LPG control system should accommodate this need.

Yes that is true..
Sparkers and Coils need to be in top form too.
And being a higer octane 100+ it can be squeezed to some degree before unintentional combustion so it's a great fuel for tuning as knock is reduced to a high degree.

Yes, but you have a 3.5 not one of the 'bored out' 94mm variety.
My well maintained 3.9 suffered terminal liner slip 12k after a professional LPG conversion, a friend's 3.9 did the same under roughly the same set of circumstances. Mine cost me a new short block + hundreds in labour, my mate sold his for peanuts as he couldn't afford the repairs.
I rest my case, you pays your money & makes your choice

Seems I’ve opened a can of worms here guys but unfortunately the car I was looking at was a bit worse than had been explained bloody people not describing things correctly ****es me off but now going to view a 4.4 L322 with lpg today. Not the p 38 I wanted but still a full fat RR, and please no remarks about going to the L 322

Petrol engines from what I read about seem less troublesome as there the ZF box not GM and don’t put so much torque through them

If it's the 2002-2005 L322 then no the ZF5hp24 is not a good box.
however 2005+ has the 6hp26 which is much superior, probably the best gearbox ever fitted to a RR

So instead of dropped liners on the P38, you can enjoy water in the electronics with the L322
