Had my '83 110 V8 converted for 5 months now & generally very pleased with it. Insurance was no problem so long as you sent them a compliance cert from LPGA installer. Sailed through the MOT (emissions done on gas only). Doesn't like starting on gas when very cold (lot of backfires) so I normally start on petrol & flick across once the engine is warmed up. Just had a problem with petrol solenoid - installer is going to refund cost of replacement on warranty. Fuel economy a little bit worse than on petrol - but gas is about half the cost at the pump. No noticeable effect on power. Need some forefthought & planning in those bits of the UK where gas pumps are few - plenty of maps & websites available to help with this, though. Tank takes up a bit of space in the back, but is OK.
