Some Possibly Helpful Information
My 1985 C4 was riddled with misguided attempts to increase power when I purchased it. To correct the problems caused by those efforts in improve performance, I ended up having to go through the engine components and electronics at length.
In B4 "I already know this/there are other threads" -- I just wanted to do a link dump of some of the stuff I found harder to obtain information about or buy so that it might help someone in the future as the items are somewhat related. I didn't include the common stuff that is available in Tech Tips (or at least super obvious to find).
Some information that I found helpful in the process is listed below:

Some information that I found helpful in the process is listed below:
- Fuel Injectors - I spoke with Fuel Injection Connection to get the correct "stock" injectors. Here is what they recommended and I subsequently installed: https://fuelinjectorconnection.com/p...3-injector-set
- Vacuum System Diagram: https://goo.gl/images/HNs3ju
- Nice Visual Walk-through of Vacuum system:
- EGR Temperature Sensor (No longer made by GM/ACDelco): http://a.co/gTv1v1x
- Cold Start Injector Pig Tail - https://www.ebay.com/itm/311784532652
- Installing the Distributor if you disconnected everything:
Thanks!

FYI, the vacuum system diagram differs per year and vehicle, a lot depends on options, etc.
A diagram sticker is attached to the top driver side of the radiator cover, make sure to take a picture of this.
