Ive been dicking with this damn car for 2 weeks now and I still can't pinpoint my issue..
It will fire right up but it acts likes the wires are crossed! it runs buts chugs really bad... I thought maybe the carb had some crap in it so I tossed the Holley 750 back on it and it ran even worse..
I pulled every plug wire at the coil while it was running to see If I had a dead cylinder but all of them were sparking and the idle changed drastically each time i pulled a wire...
The only thing I did that might have any effect on it was move the 6010 from the intake to the inner fender.. I don't believe these boxes need to be ground but I ran a ground wire from the box to the engine anyways and of course nothing changed..
How could it go from running fine one day.. Park it... fire it up 3 days later after it sat undisturbed (with the exception of moving the box) and have it run like complete and utter ***!! I didnt drop the box or anything like that, I felt it got too hot on the intake so I want it moved to a cooler safer spot..

Ok heads up apparently the 6010 doesn't like to be mounted on plastic.. I put the box back on the intake and guess what.. it runs perfect.. this is freaking weird.. Theres no way its a grounding issue if the box is grounded directly to the battery but as the titles states.. I am at a loss

I believe hes trying to say that one of the holes in the intake for the MSD box mounting is not blind tapped. It runs into the intake runner, so its producing a vacuum leak. Eric L

It makes no sense... While it was running.. I tugged and pulled on every stinking connection and there was no change... I thought I perhaps may have stretched the crank sensor line a little bit but that too proved to be perfectly fine..

Thank you sir from Denmark! So your saying I had a vacuum leak at the manifold and it was causing it to surge.. Hmmm thats a good possibility.. Considering the only change I made before it started acting up was moving the box i bet ur right!

Massen1981 Helped me out big time here, it was such a small issue that turned into such a big problem...
Im running the RPM intake btw
One of the screws that go thru the intake that hold the 6010 in place is not blind, it goes right into the port causing a massive vacuum leak... And I completely and obliviously missed it.. and Dr. Dub.. I did that I just didn't think to spray the mounting holes!!
