Reversing of the wires to the distributor. Called ignition phasing.
I was told by a number of people that was likely the cause of the drop off of power around 5000-5200 RPM on my 440 powered Belevdere. So I ran it on a dyno with only necessary timing and distributor wiring lead swapping. Made no difference as the dyno runs were 346-348 HP at the rear wheels. BTW - I had power over 6000 but it was only about 210 at that RPM and was a straight line from 348 to 210 HP.
The ignition guy was perplexed. So, don't throw that idea out the window totally.

Mine does the same thing and I swapped it back to the old points and it ran fine. I read somewhere that the two wires from the pickup can be swapped causing issues. I made my own harness The diagram I used does not show the orientation of the pickup wires. I have not tried swapping mine back yet due to knee surgery but I'm going to try it and let you know.
