Re: Gas parts
Tanks do 10 years, you will need to have it tested.
350 holley should be fine on a 6, might fail a roadworthy because 350's can't be made pollution compliant, but that will depend on the road laws of your state.
Be very, very careful with LPG. Installed incorrectly it can and will leak and blow you sky high. I would strongly reccomend having a licenced LPG mechanic install the system into your car.
Just like a Tsunami.
