I probably overall agree with Alistair because with a carburettor it will always be a compromise for the best set up for gas or petrol, whereas on the Blenheim 4 the ECU does the necessary fuel air mixture adjustments through the injection system.
I know that some people are happy with the set up on a carb but it always ends up as running better on one fuel than the other and usually starting on petrol and finishing on petrol -- needs to be monitored.
Saying that, Pauls car is such a special example, that it probably justifies the expense of converting to fuel injection and the box of tricks to make it all work properly.
Maybe it would be worth finding out if the wing bays could both take doughnut LPG tanks and the weight of the fuel safely, then doing away with the the spare wheel and moving the battery and electrics to the boot.
That would still leave ample room in the boot for the convertible roof components.
Hell of a lot of work and expense though and if you are going to go that far away from standard, maybe a nice modern common rail diesel would be the thing to give lots of power and torque with great economy !
Best leave it alone :-)
