I AM somewhat confused about LPG conversions. I run a Ford NC Fairlane and a Mitsubishi Magna on LPG without any problems, but I'm thinking of buying a Holden Statesman, which I believe would be a WK or WL model, but I have been told the Statesman can't be converted to LPG.
LIKE all carmakers, Holden advises against converting their cars to LPG unless the engine has been modified by the factory. But there are plenty of LPG specialists who will convert your car to dual-fuel. Impco has an excellent dual-fuel system for the 5.7-litre V8 using Sequential Gas Injection.
