I have converted a lot of 850's and phase 1 70 series cars. The engine you have does effect how well the system will work. 10 valve engine do not have such a smart engine management system and is harder to set the LPG system up well on.
Pitfalls, filling takes longer, Spark plugs and HT leads etc need to be in much better condition to run LPG than for petrol, you either have the spare wheel in the boot or not carry one, guys down the pub (and internet forums) will keep telling you it will ruin your engine.
Pros, fuel cost is lower than a deseasel to run, engine oil is less contaminated, emmissions are lower.
Valve seats are already hardened. After doing 100,000 miles on LPG you MIGHT find the valves are started to cut into the seats a little but likely still within wear limits.
You do need to consider the payback time. Ideally you want a 12 month payback time. With the typical cost of 5 cylinder conversion being £1200 you need to be expecting to have spent £2500 or more on petrol in the year. That would see your money back and there after you are saving money
