Grounding Straps on Big Block
 

This is kind of a dumb question, but how are the engine grounding straps connected on your 73-87? I'm working on a 78 Big 10 with a 454 BBC, and I've got some electrical gremlins*, and I think it's due to wacky grounding.

The cab-to-block strap is directly out of the cab (no exterior attachment), through the firewall, and currently is attached to a valve cover bolt (!).

The block-to-whatever is...dangling. And it looks too short to go to the frame, plus the frame over there has no OBVIOUS place to put it.

My bud tells me that the cab-to-block needs to go the back of the block. My block-to-frame is attached to the back of the block on the passenger side, but you gotta be a contortionist to get a wrench on that one, or skinnier than me.

Any help or ideas at all? I'm just going to put a self-tapper in the frame tomorrow for the block-to-frame, if not.

* The funniest one is that the oil pressure and the voltmeter tick in time with the turn signal when it's on. The worst is on that I don't have a battery terminal on my fuse block that is powered so all my fine work on a $50 pawnshop radio is moot. And the gas gauge is flaky, but I can live with that.

Cab to engine strap is off the rear of the right head to the firewall. Engine to chassis varies from a tab on the engine to battery ground cable to a seperate 10 ga wire from eng block to chassis. Radiator support has a wire from the ground cable end to the support. Run extra wires if you must but get everything grounded. This will help with rust also. Don't know why but it does. jim
