I am selling my 71 Challenger Convertible.  This car is a great driver that you can take anywhere and it is enjoyable to drive.  I have the original Numbers matching 340 currently sitting on an engine stand, it runs great! The only reason I took it out was because I took the car on the Power Tour and I did not want to worry about anything happening to the original engine.  The engine that is currently in the car is a 70 340 that is bored .040 over and built to stock 70 specs with Powerjection III fuel injection setup on a Weiand Stealth intake.  It has stock manifolds and TTI 2 1/2" Xpipe exhaust.  With the throttle body fuel injection, when you look under the hood it looks like a mostly stock 340 with a double pumper.  It has working factory air conditioning that has been retrofitted with R-134a.  The original radiator has been redone as a 4 core so even when you sit for hours in traffic in 100+ weather with the AC on the engine stays under 200 (tested this out on the Power Tour:) 

When I bought the car it didn't have the original 727 with it so I took it out and replaced it with a Keisler automatic overdrive.  I would say that putting overdrive in this car is the single best thing I have done to it to improve drivability.  The transmission works perfectly and even has a switch for an A and B calibration, one has smooth shifts and the other has much more firm shifting and higher shift points.  With the original 3.55 sure-grip and 275/60/15 rear tires overdrive cruising at 70 mph is 2100 rpm. 

The Steering box and pump were rebuilt by Firm Feel to there stage 2 setup, this summer I replaced all 4 shocks with KYB Gas-A-Just shocks, all new ball joints, tie rod ends, and had it alligned.  It has the HD Rear suspension with both front and rear factory sway bars.  Power brakes with front disc and rear drum, I just put on new front pads and calipers and turned the rotors and the rears have new shoes and freshly turned drums. 

The car is currently painted red with a black hood treatment and tail stripe.  The factory color was GA4 Light Gunmetal with black side stripes.  The spoilers on the car are original take offs from a Challenger TA, and the side scoops are original pot metal pieces from a RT.  I believe the car was painted in 83 and while it still looks good it has a few places where it is begining to show its age.  The seam behind the doors where the rockers meet the quarters is starting to swell up underneath the paint and I have noticed a few small bubbles on the lower area of the drivers door starting to show up.  Also there is the typical E Body convertible crack in the panel in front of the trunk by the hinges.  I know the floor pan has a patch in the drivers footwell and behind the passenger seat, also there is a patch in the trunk.  The lower rear quarters were replaced when they painted the car, you can see the seam from inside the trunk. 

The interior is black and still has the original 3 speaker dash which is in great condition with just one very small crack at the corner of the center speaker.  The seats are all in realy nice condition and I believe that they may be the original seat covers also.  It has Rallye Gauges that were installed by the previous owner but I updated them with the solid state voltage limiter, electronic tach board, and quartz clock from Real Time Engineering.

I know there is a lot I am leaving out here but I'm trying not to write a book.  I have more pics of the car at photobucket.com/ChallengerConvertible and right now the car is in winter storage but if you are seriously interested I can get specific or more detailed pictures posted, I will try to get more engine bay and interior pics ASAP.  I also have a small laptop that comes with the car and has the software and hardware to make any adjustments to the Transmission and fuel injection.

I am in St Louis, MO and I am asking $55k  send me an IM or email to cynister(at)yahoo.com

Thanks!
Jason
