November: Engine Update

It has been a busy few months at real work so little time for the restoration project. However, some steady prep work has been done to the 1969 date coded 340 block so the long block can be assembled in the next few weeks.

Also completed was a quick pressure wash of the engine bay which quickly revealed much of the original gold color. According to our research the car was painted over with purple in 1971 and then quickly covered with black in 1975 which means the underhoold gold paint has been hiding for most of the car's life. With some more cleaning and pressure spraying we might even see more original paint appear.

July: Drivetrain Gets Pulled Out

340 Dart Swinger engine removal

A productive afternoon was recently spent pulling out the engine and transmission from the 340 Swinger. Fortunately every nut and bolt broke free easily which made for a simpler job than was expected. Once the drive shaft and shifter linkage was removed there are only 4 cross member bolts and 4 transmission bolts to remove before pulling out the A833. Having a few hands made this is a simple job even while we laid on our backs. Since we had removed the intake and heads already we were able to pull the engine without even removing the hood.

Upon quick inspection the heads and short block look to be in very good condition with the exception of cylinder number 7 which has a stuck piston. It seems that water was leaking (or leaked) into that cylinder at some point which caused the rings to rust to the cylinder wall. We took a variety of approaches including Evaporust, AeroKroil, diesel, ATF, Marvel Mystery Oil, and let them sit for several weeks. Despite our best efforts nothing has worked to remove the rust. So, next stop for the block will be a machine shop who assure me they can get it out. Even if pitting is really bad they are able to sleeve the one bad cylinder which is great because this is a date correct block.

Some quick observations from the inspection reveal and unknown camshaft, .001 sized rod bearings, standard main bearings, cast silvolite lower compression pistons, and an extremely sloppy timing chain. Hoping to get good news from the machine shop once they've hot tanked and inspected the block.

June: Digging Deeper

The slow process of pulling the car apart continues. Recently the carpet was pulled from the interior and the heads and intake were removed to check the condition of the cylinders. Overall things look better than expected with less rust in all the areas. Watch for some "how to" articles to come up in the next few months as we undertake some repairs. We recently installed new front wheel studs as some were damaged. More to come....

May: Documenting the Swnger 340

Once we got the car home it was time to give the car a quick rinse and take a much closer look at the "numbers". From an earlier exam on the car we knew it was not a numbers matching drive train but we did know it was a date correct 1969 340 engine. We also knew most of the car options from the complete fender tag which included some pretty unique options like Y4 gold metallic paint and a V88, or stripe delete, option. A quick scan underneath revealed the correct 340 K member, correct A body A833, original torsion bars, original rear springs, correct radiator, and an the original ignition coil hiding under the seat. We also pulled the rear seat and were shocked to find a perfect condition build sheet intact and readable. We now have the complete breakdown for all the options not listed on the fender tag including brake upgrade and wheel treatment.

Coming Home!

After some negotiations and a few phone calls a deal was finally struck and the Swinger 340 made a trip to it's new home (dust and mouse droppings were free). The car looks even better outside!

Finally A Closer Look!

Fast forward a few years and many phone calls later the current owner of the Dart Swinger 340 was willing to let me come take a closer look at the car. Upon arriving I was surprised to not find the car parked anywhere. Turns out the last time i saw the car outside someone had stolen the carb off it so the owner hid the car in a small one car garage behind his property. Driving by the property you would never have guessed that hiding in the little garage was a 340 4 speed Dart Swinger. The car was remarkably complete with the entire drive train and interior intact save for a missing shift knob and a carb.

Once upon a time...

In the summer of 2010 while on a family day trip we stumbled down a side road in a small rural community and was surprised to find parked in a local business storage compound a black 1969 Dodge Dart. We could make out the painted tail stripe and noticed dual exhaust as we drove by so we stopped and had a closer look. It had a bulge 340 hood, bench seat, four speed, and the all telling LM23P9 VIN tag. Cool! A true 340 Swinger car. A few pictures were taken and the phone number for the business was copied down for future reference. I've always had a love for the 340 Swinger model. Part of this comes from growing up in a mopar family and idolizing my dad's first ever new car, a 1969 Dart Swinger 340 (read about it here).However, the appeal of the 340 Swinger was also because it was an understated muscle car. The car featured a powerful drive train but with little chrome or flashy options. Forget mag wheels, decorative options, or even comfortable bucket seats - a Dart Swinger 340 was about what was under the hood not what the car looked like.
