Aren't you doing that now??

And carb is simpler to chase down. But with the LM7 you can use the 6ls box and be able to do the adjustments to timing, 2 step, and timing retard for nitrous or boost with any laptop and the software.

One of the site's vendors is having a cyber Monday sale on all kinds of stuff so you may want to call them.

Would be better than having to pay a wrecker bill to get you back to Florida cause I don't know of too many shops that keep swap harnesses on hand!!

I don't believe the issue is bad enough to make the car come to a complete stop as soon as I moved the wiring to a more desirable place it hasn't given me any issues. I've driven the blazer over 1000 miles just in the last month just figuring out the kinks I do see a complete harness would be the way to go but 700 bucks is alot of coin for me right now just for this issue

Bp will fix you harness for you so that will be cheaper. While car is idling use an infared temp gun and check the temp of each header primary. If one is alot lower that will be the bad cylinder. That is how i found a bad coil. Ran great at full throttle but part throttle and idle it was a little rough.
