Just so I don't get slammed, this is a technical ignition question that is NON TURBO related..
350 Chevy crate motor, HEI Distributor, ran perfect before install of Summit Digital CDI Box, and MSD Super conductor wires.
I installed a Summit Digital CDI Ignition box, followed instructions to a T installed new MSD Super conductor Wires, car runs good..BUT..under load when the torque converter is locked up it has a miss, I know this is electrical because when it misses the Tach needle jumps around (more than what the motor is actually doing)
I called Summit and they had no idea, just said "make sure cylinder 5 and 7 wires arent touching" I told him their brand new wires, I did this and it's the same.
Any ideas?? It's grounded right to the battery and I hooked everything else up as instructions said.
Let me know, My only other Idea is to check Spark Plugs?? LIke I said, it runs perfect except when under load, TC Locked up you notice it....
