NGK V-Power Spark Plugs are a great fit for the 1970 Dart 340, so I would definitely recommend those. Hope this helps -Rich
check the coil pack
I believe all 340 darts had the scat pack if I remember right.
symptoms are: you can hear the engine missing, spitting and sputtering, loss of power...you can tell if it is a coil pack by unscrewing the spark plug that it connects to coil pack. when you look at your spark plug it should be a light grayish, white..this means the coil pack is working....it is best if you do this with new spark plugs, because your spark plugs could be bad. but you do this process until you find a bad plug then, that coil pack probably is the bad coil pack.
Mounted on your valve cover is a box where your spark plug wires connect. This is the coil pack
bad coil pack or bad wire
There is no distributor on it. There is a coil pack, you can follow the spark plug wires to it.

There are no stats on a 70 dodge demon as they weren't even built until 1971.
The 5th digit of the VIN is "V", indicates a 440 6-BARREL for a Plymouth (Dodge is 6-PACK).
The purpose of a coil pack is to supply the spark to the spark plugs.
hood pins were an option back in 1970 as that was the fad back then, basically just for looks on the charger but were functional on the super bee 6 pack and road runner 6 pack cars.
To change the spark coil pack on a 1998 Pontiac Sunfire with a 2.4 engine, first disconnect the battery. Then remove the coil pack and spark plug. The spark plug should also be replaced with the new coil pack for best performance. Insert the new spark plug, then the new coil pack being careful not to bump any of the many other electronic parts. Then reconnect the battery.
