Hey All people with Beautiful vans and trucks

My name is Ryan I live on the northern beaches of Sydney and iv just bought a Blue 1974 Bedford van. Im a landscaper by trade but i also play in a band and i want to make this thing the ultimate road tripper for me and the guys i play with.
It currently has a red 202 engine that runs on LPG and petrol,  but she's way to slow on the open road, I have three different ideas in mind for a new engine
Turbo Dissel
Fuel injected v6 commodore
308
i want to have her running on either strait petrol or strait LPG  and the LPG tank can not go inside the van i need all the room i can get! I also want her to have air conditioning and power steering which she does not have now

So my question is what is the best and cheapest  way to go with the engines? and can i get custom made LPG tanks to fit under the van?

If anyone can help me with some good advice that would be great!!!!

Cheers Ryanstf
