Hello Perko.
I am thinking the pickup in the new distributor is bad.
This would cause all sorts of timing issues.
If you have no mechanical noise grinding, banging, crunching, with the electronics disconnected in guessing that is all ok.
Did you check the air gap in the pick up coil ? should look the same as the old distributor?
Is it sitting in the same location as the old distributor?
If so can you swap the old pick up for the new one and see if it corrects the problem?
Is there 8 points in the center reluctor?
Does the gear on the shaft look like the other distributor?
You can also compare to this.
If needed can you reinstall the old distributor to confirm?
let us know.
Happy Mopar :)
