would anyone be able to tell me or show me where the grounds are on a 87 z28 305 tpi, or if you all have a link it would be great please and thanks

 

Usually to a dedicated bolt on the intake.

 

I think i had a ground on the back of each head coming from the harness to a bolt on the back. And two on the passenger side front of the head, i think this one is from the starter and one from the battery. i think those are the only ones i remember unless there were more then one goin to the same spot on the back.

 

like stated, theres a few on each head on the rear of the engine. one runs to the firewall as well
