This is how I ground my motors...

No Truer Words Spoken! 90% of electrical problems are grounding issues.

Re: Engine to frame ground

I bought straps on Amazon and put them where the FSM showed for a 6 cylinder

Re: Engine to frame ground

As said above you cant have too many good grounds. I go from battery to engine block. Then engine to frame with heavy gauge cable.
Then frame to cab on both sides with 6 gauge cable using ring terminal and heat shrink.
Then radiator to frame with 6 gauge like the cab.
Then frame to box for good tail light grounds. Also if you have a rear mounted gas tank/fuel pump they need good grounds.
My builds are LS swaps and they demand good grounds.

Re: Engine to frame ground

Back when I was having hot start problems, one of the things I did was to run the battery ground cable directly to a starter motor mounting bolt. I'd have to go back and see if that actually helped. The reasoning is sound, though. A little resistance here, a little resistance there...when you're running a lot of amps, it makes a difference.
