Quote: Can't you just do as you say with grounding each head to the block and then grounding the block on both sides to the chassis instead of running a whole other cable to the negative side of the battery? Learning curve here as well.
No MSD says thats not good enough,they say ground it to the -neg side of the battery only.
In a frame car thats true... but on a chassis car I just weld a 3/8 stud to each end of the chassis for a ground lead.... on the frame car most of the spot welds have corrosion in them so thats a weak link
