you should not ground to the K frame. It is "rustily" bolted to the body with somewhat rusty bolts!!!. Ground the engine to the WELDED parts of the unibody

I have an AlterKtion. NO rust, clean bolts.

I also have a ground from the engine to the firewall and a ground from the battery to the rear subframe
