I'm pulling my hair out. Long story short I picked up someone else's mess. At some point someone loved this car and then it fell into the wrong hands.
72 400/727 charger with electronic ignition
Unknown cam (but not stock, don't know specs but I can see by the markings it's an aftermarket core)
Holley street avenger 650
The car has obviously had some ignition issues, the hood is burnt. When I received it, the wiring was shade tree. Msd box hard wired to a procomp coil and distributor. I gutted all the wires, repaired or replaced back to factory. Could not get the car to run without blowing fire out the top till I advanced to 54.5 degrees. No detonation, smooth idle. 19" in park about 16 in gear.
Checked that the balancer hadn't spun, double triple checked firing order and plug routing.
Bought a new mopar distributor and stabbed it at 10* initial. Nothing, I can't even get it to fart long enough to out run the starter . Again verified all my wiring and order.
So the issue is internal, I'm assuming the valve timing is wrong. Maybe s worn timing set, maybe cams not in right, no clue. I'm throwing this out to you guys in the hopes that the mopar pros can shed some light.
