small block grounds...?

[mopardude318]

hello. im gonna wire my engine up so i can fire it up hopefully in a couple days..

i need to ground the battery to the engine, then run a ground from the engine to the k-frame. then do i run a ground from the back of the passenger side head to the heater blower motor bolt stud? i think thats how my dart was at one time....not sure..

how are your guy's cars grounded? and where does everything bolt to and from?

pictures would be a plus if ya got any....how did the factory do it?

You really cannot have to many grounds. I would run more than just the engine to the blower motor. Maybe run from engine to fender well. Don't make them very small, either.

I added one ground wire to that list.

a short, 10 gauge ground from the battery to the radiator support - I just used a radiator bolt.

All of the lighting is grounded up there, headlights / turn signals / parking lamps. Just made sense to me to add that one, rather than rely on several 40 year old spot welds & several feet of sheetmetal.

I ran heavier to the firewall and a battery cable from the head to the kmember. That solved my battery in the trunk problem.

Really? How well does it spin the engine when hot? I was thinking of a battery in the trunk on my Dart. All of them I've ever seen done had a bit of trouble spinning a hot engine.

I have my battery ground in the trunk,also a ground strap from the head to the old battery tray hole.Cranks up every time,hot or cold.I,m also running solid mounts,so I,m sure that helps grounding also.:burnout:

Grounding to the K frame doesn't do a thing. The K frame is bolted to the WELDED unibody, all of which is one big piece, except for the front clip, doors and trunk. There is no other electrical "stuff" hooked to the K frame, so this is a dead end, and if the bolts get rusty, there you are.

You need the MAIN ground from the battery to the block, whatever you do. My front battery has the main to the block. I have a no4 starter cable (downtown store) from the rear head to the studs on the brake master mount, and a second no10 ground from the batt neg. to the fender

I used to run my Roadrunner, 440 6pak with a trunk mount bat. and that thing didn't have any trouble cranking, hot or cold. On it I had two "6 volt size" cables, store bought starter cables, grounded from the block to the unibody. This was 30 some years ago, but my recollection is to a bolted through hole on each side of the firewall
