How many CURRENT owners of real '74 360 Duster 4 speed cars on here?
The problem with just looking at images online is that most of these cars have been changed a lot from when they were originally built. Yes, nowadays almost every car with a stripe has the engine size designation below the stripe. Not because it was originally equip'd that way, but simply becuse it looks far better. Plus the fact that any engine size call out, even custom, are included in the price of a stripe (free!), who wouldn't add them on? ...unless doing a OE Gold correct resoration.
Really, on any true performance Mopar, the more you break them down the more most cars become nearly a 1 of 1.
