Hi Guys,
on a 89 SWB I ran an impco system which i put together on a 4.2 petrol for 500,000km's. Getting about the same range on fuel and petrol depending on tune and condition of ignition system( VERY VERY IMPORTANT ON GAS, get the best you can buy) a 115 litre tank which replaced the origional fuel tank, it ran dual fuel through a 300a mixer. bigger exhaust, excellent ignition and extractors help heaps. Shave your head, even better, but get your dizzy regraphed to suit LPG., cam ( but standard works fine)
the Small block ( or bigblock) needed a bigger converter and dual impco 425 mixers, still on dual fuel through a holley 850 double pumper. the single 425 didnt cut the cheese, but i wrecked the car before i got a chance to fine tune it. I will slot either the 454 or the 350 in again soon.
You can braze up a fitting and install a couple of inline solenoids to enable you to use a 9litre barbie gas bottle for emergency's if your running straight gas, you can also use this system to fill barbie bottles for $3.60 instaed of paying $25.
Go gas, and dont look back, Impco, Gas reasearch, ect are all good, some are better for specific applications. You can go psyco HP with high compression motors running straight gas, industrial mixers with separate idle circuts oto, the modifications and performance is virtually endless.
The standard 115 litre tank ( 95 usable when your AFL is working correctly) that mounts in the origional location hangs down a bit but weld up a big arse bashplate or move the mounts up if you have a bodylift.
I never had any problems withit, Gas, safe as houses.
For a fueltank, chuck in a Fuelcell, again, safe as houses.
