'70 Dart 392 Project; what direction?

Alright now we're getting somewhere!
I had the idea to test the voltage at the connector on my daily driver (ram 1500 5.7hemi) and was getting 5V on signal and 5V on reference. I was only getting 2.39V on my signal wire.

Called DIYAutotune and talked to Steve. He had me jumper in a 3K resistor between the signal/5v ref wires and bingo 4.98V on the signal wire. Same thing on the cam sensor. RPM successfully sync'd!

While testing coils the aftermarket fuel line quick connect plastic fitting on the fuel rail let go and shot a 60psi stream of fuel all over the engine bay and myself.... that was fun, glad I wasn't actively testing spark at that moment! Grabbed the OEM connector clip and no more leaking. Got that problem solved.

Tested spark and no spark. Went through wiring diagrams and while I had everything connected according to MS manual, they don't reference a relay activated power source for the coil packs. Spliced into the O2 sensor relay to the coil packs and boom we've got spark!

First crank and she caught and fired right up! to 3,000 RPM's..... forgot to plug the old MAP sensor port on intake. Got that plugged.

She revs good, has 60PSI oil pressure, no leaks anywhere. Progress!

Now the bad:
After she catches kpa reading on MAP goes to about 30kPa. Not sure if that's normal or indicative of another vacuum leak.

She fires to 800 RPM then after a second climbs to 1750rpm-ish.

My O2 sensors are reading Error 9. Low voltage. Need to dig into the relay wiring with my meter and see whats what.... Pulled a datalog and will try to interpret what I can find.

Also now that everything is confirmed hooked up correctly (minus the O2 sensor voltage issue) I need to wire loom and high temp tape some wires before I dig into tuning too much.

I went ahead and put the header collectors on and slipped the Borla muffler onto the collector extensions for now to try and get an accurate O2 sensor reading. Won't be able to tell until I get the voltage on the O2 controllers where it needs to be.

Thanks for the help everyone! The saga continues....

Awesome! I know it’s a great feeling when they finally make noise.
I guess I forgot I have pull up resistors on my cam and crank signals from when I ran the small block. I have them made into the harness inside the car.
30KPA is normal. Mine idles around 45 and I have an aftermarket cam. 100kpa is atmospheric pressure, so wide open.
The rising rpm sounds like the IAC is functioning backwards.
