Has anyone had any experiance with lpg on a 4age as i am contemplating doing this (as the 4age is in a zook 4x4). I was thinking it would be better as i wouldnt have any problem with fuel starvation going up steep hills or on steep side angles. Would i have to modify the motor in any way or will it handle it ok? Are there any cams that are designed for gas useage (as i will be running straight gas and no petrol)? Any help would be greatful.
