340,to stroke or not to stroke

Well said Moper, most people over look it.

340s are rare, I have only found 1 in my area the past year and the guy wanted a life savings for it. But if I understand you correct, you have 3 340s? I know how you want the same date coded engine in your Dart and respect that so here is some insight to help you decide. The '69 340 was only avalible in Darts and Cudas. The 70 was avalible in Cudas, Darts, Challengers, and Dusters. The 73 was avalible in Challengers, Cudas, Dusters and Dart Sports.

With that said, I say number one, depending on pocket money, build the 69 340, since it was the first year in an A-body. Number two, dont over bore it, just enough to clean it up. Weakens the cylinder walls, so in turn it cant take much abusing, aka fun. Number three, I would piece together my rotating assembly like I have done for 1 engine and getting ready to piece another one together. If you are set on a whole package deal, you have Speed-o-motive, Hughes, Hensely, Mancini, Muscle Motors, Callies, Ohio Crank, and 440 source. Not sure if they all deal with 340s but they all make rotating assemblys. Number four, plain and simple, ITS YOUR ENGINE! O WITH IT WHAT YOU WANT, I have people telling me why are you going to restore the 70 Chrysler 300, its a boat anchor, gas hog, well I am doing it cause I love it and if you love the idea of having a 340 in that Dart, then by all means do it, just dont blow it up haha.
