67 twin turbo dart

When I had the cam made, it was suppose to be done in the LS firing order, guess the guy at the CNC machine didn't see that note and just saw small block Mopar. So I had the coils and injectors wired to LS firing order, the can ended up being factory Mopar, so I had to rewire it all back to factory. So the dark cylinders they saw weren't rich condition they were firing on the wrong cycle, which explains why the inside of my intake to throttle body was jet black.


Wow! Glad you finally figured this one out. You sure went through a bunch of troubleshooting! Kinda explains the sluggish performance. Small blocks usually run better as an 8 cylinder instead of 6.
