WHAT internal changes have to be made to a standard AU III Falcon six-cylinder petrol motor to convert it to gas? Also, what is the best gas system for this conversion, and who would you recommend to carry it out?
CONVERTERS make no internal changes to the engine when they convert it to dual-fuel, and plenty of cars out there are running on LPG with no problem, so I wouldn't be worried about engine wear, if that's your concern. The most popular -- and the best -- system is an air-valve system. Impco has a nicely developed kit that is easily installed for about $2200.
