Best straight gas setup for 265?

[Ext User(Andy)]

G'day,

Was wondering what the best gas carb/mixer would be to run straight LPG
on a 265 hemi. Brand names and all, I'm new to this.

All help appreciated.

Cheers,

Andy. (The other Andy.)

Thanks for that Athol. Seems that most of the second hand tanks
available are generally APA. Yep, already a fan of the hotter
thermostat (just put a new 195 in there on Saturday.)

Extractors and 4 barrel manifold are already on the cards.

Now to find a "flexible" fitter. Engine bay stuff looks to be straight
ahead stuff.

Thanks again,
