LPG and turbo
LPG carb is a sealed unit Impco do a 425 which flows approx 460 CFM
cost about 150 you need a rising rate evaporator plumbed into high pressure side of turbo
run 2 of each if ya like
they bolt onto holley style throttle plates easy.
the throttle plates need to have the bearings sealed.
you can weld so i guess turbo manifolds for the exhuast end of things is no bother
standard manifolds modified with steam pipe and a flange
the engine is not exactly at CR associated with turbo use but you are running LPG which has a much better octane rating.
you will want to lock off the ignition timing at approx 10 BTDC
easy done
pick up a standard Aussie Mopar ELB dissy. this is a distributaor with no advance mechanism built in. used on Electronic Lean burn Models (mid 70s ECU)
or use a ford edis module and trigger wheel in limp home mode.
or just wire/spot weld up the weights in your current one
Tank can be had off ebay
filler can be mounted into the current filler
lock off and braided pipe for install can be had from LPG installer
run it till the valve seats fall out 50,000 + miles
or get an LPG cam (very gentle close profile on the exhaust lobes)
or run a flash lube injector. just like water injection but includes and upper cylinder lube
you then go really quite fast with a 318
the forced Induction chat here is interesting

LPG install costs £2000 if you gop to an installer
it costs about £500 if you get the bits second hand
this fella does second hand front kits

don't make the mistake of thinking this gear is the same as on a forklift or a dual fuel Jeep. proper gas carb with metering rods a diaphraghm not some gas cooker ring bolted into your air filter
its an aussie car
go fast the ways aussies do
