Defenders are looking alot cheaper for me to insure, there is a nice 3.5 v8 carb just would have to get it converted to LPG, can a carb v8 have a multi point system fitted or have to have a carb mixer set up ?

Got to be a 2-point carb feed, multipoint sysyems normally use the petrol injection ECU and switch the petrol injector feeds to the gas valve blocks, MAF and the other sensors are all used, just as in a petrol engine.

There are a few with their own Gas ECU, but not many at all.

PS: I'm not up late, I'm overseas at present.

You could of coupe change your inlet to a efi system from a 3.9 range rover not as difficult as you may think. Then you could fit multipoint injection.
