The blue/white one probably has a 302, as it lists it on the car. Of course, the owner may have swapped out engines by now.
In the third pic, behind the white one, you see part of a early 70s
Ford Mustang...I don't know if those were ever exported to Australia. I think they look similar to the Falcon, but Wikipedia compares the Falcon to the
Ford Torino...I definitely see the similarities there.
Starting in 1971, US cars started losing a lot of their power due to detuned engines (to handle unleaded gas) and emissions controls. Did Australia go through anything similar?
We've had one Holden come to the States recently...the Monaro was sold as the
Pontiac GTO. It's a nice car, but shouldn't have been sold as a GTO given the GTO's history. The new
Pontiac G8 is based on the same platform as the Commodore, and is being built in Australia to be shipped here. The Chevy
Camaro and
Impala will also be on the platform, but are going to be built in Canada.
