Very hard to define.

Is a HT Monaro a muscle car? Most would say yes. But what if it only had a 186s engine. If that makes the answer no then is it the engine that makes it a muscle car?

If this is true then an 308 Sandman is as much a muscle car as any of the 308 Monaros.

If it is just based on the body then an LJ Torana 2 door no matter what description is a muscle car.

Does it have to race around Bathurst? That discounts a whole bunch of 1970s Holden 4 doors.

Does it have to be the body shape and the motor combined. Therefore a HZ Monaro 308 sound like it meets the criteria but what about an HZ Premier with a 308.

Very hard to clearly identify.

As time goes on and the divisions become more blurred I think a Sandman could fit the bill to be called a muscle car. It has the motor, the sportiness factor, just missing the race history.
