Last friday I popped the hood to show a buddy my engine swap and noticed I had a nice spark jumping from my trans dipstick to my firewall. That makes me feel like my engine isnt grounded properly. Right now I only have a ground from one head, to the battery. I plan on grounding the starter and the other head, but is there anything/anywhere else I should put a ground wire? I have about 20 feet of 6aug wire that I will be using. THANKS!
You should ground the engine to the frame, and ground the body to the frame. One #6 wire for each should do the job. You only need one ground connection for each, don't overdo it. Ask an electrical engineer about "ground loops" if you want to understand more.
Did your engine have a miss as well? You may have a plug wire arcing against the dip stick...just a thought
Im running a few good sized grounds One from the engine block to frame one from the ground on the starter to the frame one from the frame to the body one from the battery ground to the frame I also have some intermediate grounds for all 4 corners (like 14 Guage) of the vehicle running off a grounding block in the harness just in case its needed
What he said. Normal 12 volt current isn't going to jump a gap like that. There is a high tension leak, of some sort, going on. You may have a bad ground somewhere, but it isn't causing that problem
If you're engine is grounded with a wire from one head to the battery, that is good enough. It sounds to me like your frame and/or body aren't grounded well, though.
Put a digital volt meter on volts dc and measure between the block and the frame,if you read more then .5 volts under a load the ground is bad.
