The seller of this 1973 Plymouth Duster provides several details about what powers this mighty Mopar, and rightfully so, as this is one mean machine that’s said to be pumping out over 600 horsepower.  What he doesn’t elaborate on is how sleek this one appears on the outside, but the pictures show a nicely crafted paint job plus a rare factory exterior option, so you’ll also look good while you pass everybody on the street or at the track.  Reader Rocco B. spotted this 1973 Plymouth Duster here on Craigslist in Eugene, Oregon, and we’d like to thank him for sending us the tip!  The owner is asking $28,500 here, which doesn’t sound unreasonable if this is the sort of muscle you’re in the market for.

The seller mentions that the Duster was received as part of a trade, and although no specifics are shared, it makes me wonder if he didn’t have something quite desirable to tempt the previous owner to let this one go.  There’s very little information provided regarding the sheet metal, such as whether any bodywork has been performed or if it’s always been this straight, and it’s a real treat to find a factory sunroof on top.  No word on the paint job either, but the red finish with a black hood works well here, and the quarter panel stripes with “Terrifier” inlaid are a fun touch as well.  Both bumpers have also been turned red, so this one seems almost as ready for show as it is to go.

Springer Performance & Machine of Eugene, Oregon, is responsible for building what’s under the hood, which began as a 340.  They stroked it out to 416 CI and added parts that resulted in what the seller says is a dynamometer reading of over 600 horsepower, with 110 octane racing fuel listed as a requirement for proper performance.  The only tidbit we get about the transmission is that it’s an automatic built for drag racing, but the seller also states there are numerous stacks of receipts available, which I’m sure give more information.  It’s stated that this project cost over $30k for just the engine alone.

The factory seating up front has been replaced by a pair of racing buckets, and while it hopefully will never be needed, a rollbar has also been installed for safety assurance.  From what I can tell, the floors appear reasonably solid, so hopefully, the platform and underneath components are also sturdy enough to handle this kind of power.  The owner says that although this one can be operated on the street, it’s built for drag racing and not daily driving, but it sure seems tempting to get behind the wheel of and hit some city pavement from time to time.  What are your thoughts on this 1973 Plymouth Duster, and the mods that have been made here?
