1970 Plymouth Duster 340 - Numbers Matching Restored on 2040-cars

This is a TRUE all numbers matching absolutely pristine 1970 Duster 340.  It is stunning with no expense spared.  Every part that was upgraded or replaced on this car has been safely stored away and comes with the car.  If you want to put it back to concourse correct you can do it in a weekend.  This car is AMAZING and it wins "Best Of Show" everywhere I take it.  It's that good.

This Duster 340 was built on June 12, 1970 (Friday) at the Las Angeles, California Plant.  It is a factory undercoated car and consequently has no rust.  It has been well preserved.  It is very original and you will be hard pressed to find a better example.  You certainly won't reproduce this car for under 50 or 60K. The car handles like new.  It does not rattle, squeak, wander, shake or make strange noises going down the road and it tracks perfectly straight.  It is easy to drive, does not overheat and is blistering fast. Everything works including the radio.

You can find videos of this car by searching “ Dave Mitton Duster 340 ” on YouTube.  Here you will find videos of the final assembly for the heads.  Intake was prepared by the same shop and port matched to the heads. Also, you will find a couple of walk around videos of the car and even a launch video of the car.  Keep in mind that the launch video was shot in front of my house in Utah at an altitude of 5000 ft.  The car performs much better at lower elevations. Also, that video was shot when the car had the stock 11” 1200 stall converter in it.  I have been nice to the car.  It has not been driven hard.  It has never been to the track but with the right tires the car will easily go in the mid 12’s no problem.  This car is real fun to drive.

The car does NOT have a build sheet please don’t ask me I do not have one.

340 Engine is original to this car Numbers Matching H Code.  It was cast on Wednesday March 4^th 1970 and has been freshly rebuilt bored .30 over for freshen up and still retains it’s original forged crank and factory rods. Real deal 340 HP engine here.

Transmission is Numbers Matching and original to the car.  It is a recently refreshed 727 Torque Flight Heavy Duty 3 Speed Automatic with a factory original console shifter.

Rear End is the original 489 Sure Grip with a brand new set of 3:55 US Strange Gears.

The carburetor is a Quick Fuel 650 but an Edelbrock 600 comes with the car if you want to put it back for the factory look.  The Quick Fuel does wonders for this car. No kidding.

Intake manifold is a hand ported and port matched Edelbrock RPM Performer.  The factory original intake also comes with the car if you want to put it back.

The radiator is the original 1970 340 Automatic with a date code of Thursday May 21, 1970.  It has been absolutely and perfectly concourse restored by Glen-Ray Radiator and upgraded for maximum cooling capacity.  It is absolutely breathtaking to look at and works even better than it looks. The car also retains it’s original fan and shroud.

Heads are professionally ported polished and port matched Edelbrock Aluminum RPM Performer.  Compression is 10:1 and the car comes with a set of vintage 340 heads if you want to put them back.  They are “J” Heads not “X” Heads.

Exhaust Manifolds are TTI Ceramic Coated Heat Barrier Treated Headers fed into a 2 1/2 Inch Complete TTI X Pipe exhaust and tips going through Turbo Flow Mufflers.  The car also comes with it’s original HP 340 Exhaust Manifolds if you want to put em back.

Stall Converter is a 10” 2800 Stall that works wonders for this car.  The factory original 11” Converter and flex plate also come boxed up with the car if you want to put em back.

Axles are original to the car small bolt pattern axles that have been upgraded to green sealed bearings. The original Tapered (Timken) Bearings also come with the car if you want to put em back. The left hand threads have been converted to right hand threads on the left side of the car. 1970 was the last year for left handed threads.

All hoses and clamps including PVC, Heater, Radiator, Power Steering and Spark Plug Wires are date correct and concourse perfect for the manufacture date of the car. No detail was overlooked here.  The engine bay on this Duster 340 is it’s best feature.

Ignition has been upgraded to electronic including a new state of the art “Rev-N-Nator” box.  This is a very nice upgrade that looks like a stock Mopar Orange Box, but gives you the added benefits of a rev limiter and an internal electronic flywheel that manages the timing curve perfectly keeping the initial advance at about 18 and total advance at about 36.  Amazing product.

Rally Dash is original.  A tachometer was added and looks factory correct for the car but the original tachometers delete plate also comes with the car if you want to put it back.

Steering wheel is currently a wood grain "Tuff Wheel" but the factory original 3 spoke A-Body only steering wheel is flawless and it comes with the car if you want to put it back.

Spare Tire looks to be original to the car but as you can see from the pictures is practically perfect in every way.

Please don’t send me messages telling me that the car has “Cragar Mags” instead of Rally Wheels.  I know that. The correct set of wheels and beauty rings can be had for $1200 at Coker Tire or Wheel Vintiques.  If you want em . . . . I will purchase them for you and have them on the car when you take delivery.  I happen to like the period correct Cragar's.

Please text me with questions.

Thanks for looking
