yeah, I remember something about that but, IMO there needs to be a big ground from the block to the battery for the starter load. Then a good path from the block to the firewall for sensors, outputs, etc. The Vortec has the fuse block and PCM under the hood where TBI's are inside, so there's a difference in paths there too.I think it was on this forum somewhere or maybe another and it was pointed out that these grounds were setup in specific zones and changing locations was not a good idea.
On our Harleys, some of us do a redundant ground from the frame to the battery as you described. The electric gremlins that rear their heads typically go away, especially in the starting circuit on the older bikes...We increase the wire gauge for that too.yeah, I remember something about that but, IMO there needs to be a big ground from the block to the battery for the starter load.

The factory setup on my 96 has a ground direct from battery to front lower block. That is part of Big 3 kit. But, also, factory setup has a ground strap from rear head directly to frame.I think the tl;dr on ground planes is "don't daisy chain your grounds".
If you ground your body to the transmission, the transmission to the engine, the engine to the frame, and the frame to the battery, you could have trouble. The frame is a safe collection point for grounds, but I do like running a ground directly from the battery to the engine as well.
I thought that too, but still in the end my truck does have a dedicated ground from battery to front block. For whatever reason GM also added the frame to head ground. Since there’s no evidence other than opinions, it just seems best to follow original plan.In the thoughts of gaskets getting in the way of a ground, how about all of the bolts holding the intake manifold and heads in place?
And that's a good plan tooSince there’s no evidence other than opinions, it just seems best to follow original plan.
I interpreted that location to be a Frame to body ground for the new cable. I left the frame to head connection and replaced the frame to body.Can someone explain how this ground strap installs? Red line is original from frame, goes down a bit and under exhaust manifold, then goes up through a metal tube/wire manager and exits going up and bolting to head. The new 10 1/2” black ground strap is seen in picture and clearly doesn’t have the necessary length.
