The Ford Mustang has fans the world over, but Australia is especially fond of the original American pony car. Many examples has been imported to the Land Down Under, and while many keep their original engines, others are heavily modified to fit life in the Outback. This includes right-hand drive conversion, Australian motors, and alternative fuels.

In the case of John Colaidis, his ‘65 Ford Mustang encompasses all three of these Australian touches, utilizing a turbocharged Falcon inline-six engine, propane injected, and right-hand drive for Australian road use.

Yes, this is a Mustang with the famous Falcon 4.0 liter turbocharged 4LTR engine, mated with a Garrett T51 turbocharger. At 29 psi, and running LPG, or propane gas, this American import made over 630 horsepower to the wheels. Yes you read that right; 630 horsepower from a six-banger running on propane!

And as this in-depth article over at FullBoost.com.au showcases, there is more to this Mustang than just an engine swap. From front to back John’s Mustang was restored the right way, and the suspension and handling systems were brought into the 21st century. It’s kind of weird seeing a six-cylinder Mustang make so much horsepower without that big V8 rumble…but we like weird, and this Aussie Mustang is about as weird as it gets.
