vic,

my wiring project has been delayed, but hope to get the battery to trunk then start the aaw harness in the next couple of weeks. If you could rewind for me here...did you run a ground wire from the trunk up to the engine block or just run a ground in the trunk and a seprate ground from block to frame? Didn't see it, but may have missed it. Build is coming along nicely. Your attention to detail and patience is what i will strive for!

Hey Cav.   If you look back at the pictures I posted over the winter, you can see what I did.   If you need more, let me know.  To summarize:

I grounded the battery locally in the trunk to a support bracket, using a tapped hole and a bolt.  I ran a wire from that to a ground terminal block in the trunk.  The stuff that is mounted in the trunk is grounded to there.   I also had several items that needed to be grounded directly to the battery that were in the front of the car.  So, I ran a ground cable from the rear ground block up to the front of the car, and installed another ground block there.   This is used mostly for electronics, as I have a VHX dash computer, the Vintage Air computer, a digital ignition box, and EFI computer that all should have a solid, separate ground to the battery.    

In the engine compartment, I ground the "power" stuff locally.  I am running my block ground from my starter mounting bolt, directly to the frame.   

Here is my ground block diagram

So, VHX is for my digital dash, VA are my Vintage Air Grounds, P2 is my Pertronix Digital Ignition Box Ground, PWM is for my Pulse Width Modulation Fan Controller, Pwr Amp is for my Rockford Fosgate 400 watt power amp.  The line that runs from the trunk terminal point 4 to the dash terminal point 7 is my "back to front" ground wire.  All my power and ground stuff is routed on the right side of the car, my low level and control stuff is on the left side of the car.

Hope this helps...

Vic

Vic,

thanks! I must have missed how you did the grounding with the busbars earlier in your thread. Great idea and had not thought about doing it that way, but makes sense now. appreciate it!

If I did not have all of these digital boxes, I would have done it differently, but if you don't have a good ground, you will find out the hard way.  

Let me know when you get started in earnest on the AAW harness.  I have lots of lessons learned.  If you know how to use Excel, I can send you my spreadsheet, and then wak you through my approach. But, I mapped every wire on the harness.

With the weather getting nice, moving slow on my '70 project.   Got the trans under the car today.   Once I get it secured, then will drop the front of the car down, and get the engine in.  Memorial Day weekend is looking like the perfect time to do this.  Have to get my '68 cleaned up to take to Carlisle.

I dropped the 302 with a small case c6 into my old 70 all bolted together ,actually easy ,even slipped in headman long tube headers just before the moter seated ,i left the headers loose then tightened when the motor was bolted down . Saved a lot of time ,use a lot of blankets to stop scratches

I have done that before also.  This time, I want to drop my engine in with the serpentine system and headers bolted on, and will need to steer around the Borgeson steering box, and center link, and a fully detailed engine compartment, engine and trans.   So, will do it the hard way.....

Car is on the ground on suspension and all 4 wheels for the first time in over 25 years......   Final detailing under the car is done, and the transmission is in.  Going to install my door braces tomorrow, and prep my engine for install.  I need to get my new oil pressure and water temperature sensors in, put the headers on, adjust my serpentine belt drive to include my power steering pump (it’s been disconnected on the test stand).

 

Then I will pull the engine off the test stand, remove the old bellhousing, install the new adjustable motor mounts, and install my torque converter.

So, Sunday, the engine goes in.....  yahoo....

Got my serpentine drive sorted out.  I had bypassed the power steering pump while the engine was on the test stand.  Now I am trying to figure out how to route my heater hose line from the water pump to get around my alternator....  Any suggestions would be appreciated.... will probably post something on the technical forum.  Also got the door braces from Mike (Latoracing) and put them in, as I will be dropping the engine in and don't want anything moving around...

Nice project. Where you run your battery cables through the pass. side A-pillar will this interfere with the dash installation? I ran my power cable throught the channel in the rocker up to the A-pillar but I'm encountering a wall just inside it that's preventing me from going further.

It sounds like that’s where your rockers meet the torque box. You Should not drill through there.  That is also where your cowl area is and your air vents are.  All the factory wiring runs up and threw those small holes by the door hinges.     The dash should fit fine

 The summer months are slowing me down on the project, but the engine is getting ready to go on the hook and get dropped in.    Installed my main ground wire to the chassis, and my flexible dipstick, and my vacuum modulator line. Just things to get out of the way so I can do it without the engine in.

 The main ground wire is attached to the front frame rail with a 5/16 inch body bolt. I drilled and tapped the hole to make sure I have a really good ground. (0.4 ohms). I insulated it with DEI thermal wrap, as it will be terminated to where the starter is mounted to the block    Runs really close to the headers    

Also got my billet grille  and my deep sump C6 transmission pan back from  the powder coater.  

Hope to get the engine in over the long weekend so we’ll see what happens.

Love the grill, where did you get it?
