2nd Chance Camaro - Let the Project Begin

[syborg tt]

Having to make the last cut on the fuel line was fun and yes I was worried about cutting it to short.











This was the final line which goes under the throttle body.








I also want to make sure that the line wouldn't rub on anything.

Making sure the last bit of wiring under the intake manifold will be safe from harm.



If you look closely you can see the fitting that Holley supplied are useless.



When we build in the intake tube we are going to weld tabs under the tube so we can zip tie the MAF wire harness under the tube.





I also ran the Drive By Wire harness under the manifold.





All of the wiring has been heat wrapped going to the starter.

Looking good Marty!

Looking good Marty!

Thank you Andrew and I am hoping to work on it tonight when I get home

man...I wish my car was that clean... nice job buddy!

Thanks Martin it's nice having a clean work surface

It looks sweet Marty! Getting close!!!

It looks sweet Marty! Getting close!!!

Thank you Wayne

I found these clamps on Amazon and they do a great job securing the lines.





Checking for clearance under the upper control arm and there is plenty.








Yep, I cut the wrong length of the heat sleeve when I made my last cut so now I have to order more.





So, I jumped over to the battery wires as I needed to do something a little different and then I called it a night.

Thank you and I am finally seeing the light at the end of the tunnel and it's not a train.

Wayne, how did the surgery go ?

[syborg tt]

Cylinder Head grounds are complete ( 10-30-21 )





JIC anyone wants to know this is the size of the bolt that is on the back of head.

I'd suggest moving the disconnect to the negative terminal on that battery. And, assuming the second set of wires on top are going to the fan. Is there a fuse/circuit breaker for that pair?

Ya know I have been going back and fourth on this for weeks if not months. For years I have done it this way but that doesn’t mean it’s correct. Any chance you can help my brain and explain to me why it should be on the ground side. Which I feel is where it should be.

The same reason that GM went to ground switching - inrush current. It's harder on components to have current rush through than it is to have current present. Think of it this way - electricity acts a lot like water in a hose. Voltage is like pressure, and current is like flow. Say you have a 100 ft water hose that's empty, and you turn on the faucet at the wall. When you open the hose sprayer on the other end, it jumps, kicks and spurts until the hose is full. For a short time, you'll even see more pressure on the hose than the water main makes due to the water's velocity as it goes through the hose. When it slams into the end, it pushes pressure back down the hose until everything equalizes. That would be a positive switch. On the other hand, if the hose is already full and you pull the hose sprayer trigger, it sprays smoothly. That would be a negative switch. Inrush current will act much like water rushing to fill an empty hose, and it apparently causes enough problems that GM was willing to spend the money to retool every car they make to use positive switching.

About the only place you'd want a positive switch is on a racing emergency disconnect - the idea being that in an emergency you want power killed completely. The disconnect should isolate both the battery and the alternator from the power circuit because the alternator should be connected directly to the battery and not passing through the disconnect. When the disconnect is opened, the alternator's output wire is no longer connected to the car's electrical system. An emergency battery disconnect is only concerned with not catching fire, not component life.

Thank you, Thank you

I am not sure you could have explained that any better for me as I feel like i completly understand why and this is why I love these boards.

So on a side note what is your toughts on leaving it and just adding another one on the ground since I don't have a master disconnect ?

Planning ahead before I run over to Ace Hardware for some fittings as the one's that are supplied are useless.





So the Earl fitting that I happened to have looked like it was going to work. However, It did not as it hit the valley cover.





So I found my Mike Norris Catch can and I used these fitting to start mocking up the fittings I needed.





After a quick trip to Ace I think I have the fittings I need.





Only at Ace can you find a 1/8" Hose Barb (trust me I looked everyone else)





First Mock Up

[syborg tt]

I had time to do a couple simple projects so out to the garage I went.







I decided to mock up some of the hoses.



Thankfully the auto parts store is close



Nope, I don't like the way this hose looks.





I ordered this custom hose with all kinds of crazy bends in it.

[syborg tt]

Way back somewhere in this thread I installed Painless fan relay and I screwed up and didn't order a standard fan relay. So I ordered a new Water Proof Fan Relay kit.





Since it is in between the battery and the radiator the batter once again needs to come out.














Thankfully I used a weather pack connector as I was able to just remove the ground from the plug.

[syborg tt]

My molded hose arrived










I also received another fitting for the Fuel Pressure Sensor




Looks like I need a longer hose.





Found an all in one fitting that will be replacing two of the fittings.

[Motown 454]

It looks like you got a lot of stuff figured out in the last few posts. That stuff can drive you crazy. It looks good.

[syborg tt]

Since I keep the car on the optima charger when it is parked in the garage I decided to mock up the wire and see if I could hide it when it's not in use.






I can easily tuck it in the frame rail when not in use.
