Here's another one from that article and has anyone ever heard this about the K-frame being "relocated" in the M-Code Dart and I guess Cuda? The way I read it is the K-frame was not modified but relocated in the engine compartment. Does that mean bolted in a slightly different position to the chassis? I also think there is little or no room to move the K-frame left or right but only forward or rearward where it is bolted but that would upset the entire driveline even if it was an inch or less, but would that matter? Don't think this is a true statement but.......................what's that "never say never" thing...........
is that a washer under the air cleaner wing nut.......
This is first time I have ever heard of a "k-frame relocation", who is the author of this article? I have helped restore a few factory 440 Darts both 68 and 69 and the factory 383 k-frame had no changes that I could tell...
The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
