Byron, I run several newer Holdens with both the 304 EFI motor, plus an injected LPG dual fuel system. It has got to best the combo out there. It is both bullet-proof & economical.

Hi Doug, I don't use my Sandman as my daily driver so it tends to be used for a cruise. I suspect the cheapest part of owning the car therefore is the petrol. If your a bit the same it would take another 35 years to break even on the cost of fitting. I measure the fuel economy in "Smiles per gallon"

I wasn't talking about the new injected LPG system on an injected engine, I was referring to an old carby 253 with an old style gas system on it. Can you actually fit LPG injections systems onto an old carby fed motor nowadays?
