Check out my car and talk to me about 318/340 swap

You can build a /6 to run with a 340 but, the 340 is the most respected and generally the most desired small block v-8 mopar of that (maybe any) era. Even brand Xer's are somewhat envious of 340 mopars.

Ok, I have two YT video recommendations for ya first "Bud Lindemans" test drive 69 Dart 340..watch all the way through till they run the 4 speed car,

second and not so entertaining... any video of Uncle Tony running that Plan Z "porta potty" slant Dart down the track...then come back and tell us which one you'd want to have/drive...
