67 twin turbo dart

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.
Yeah plus its way more efficient lol before I started it I went through the computer again and tested each injector and coil just to verify again that everything now is back to factory Mopar firing order. Will get it all finalized this weekend, maybe even drive it around the block. Have to reseal the right front fitting on the caliper it started to leak a little so off that comes and will seal it up with the good stuff I have for brakes and hydraulic fluid.
