the car runs well enough i can drive it to and from anywhere. it just randomly stumbles out with a cam sync error of 40+° which would equal massive engine failure if that occured. as cam is huge and pistons are close for comfort. im assuming its sync error.
also assuming ground issue with i/o harness being wrongly pinned from holley or broken wire i cant find or trace to this point

I’m amazed that you still think the harness is pinned wrong after all the comments. The cam/crank sensor leads are super sensitive to RF issues if not shielded and even then, if near a plug wire you could have issues and it was already pointed out to go to a resistor plug. Bad grounds just compound rf issues.
