Another update. #829 is just about done. The hood will be installed once I can get the car over to the body shop. The Cobra gods keep raining on my plans. I now have about 72 miles on it while doing short runs to check for and solve any issues that came up. The most annoying was the motor would misfire over 4000 RPMs but ran super below that....With the help of some members from here and my mechanic friend, it was finally figured out. I did all tests I read about and were suggested to me. After finding nothing, I turned to my mechanic friend and dropped off the car for him to solve. He checked everything and then came across the issue... low voltage issue. I am using a PerTronix ignition, their epoxy coil and a ballast resistor they note should be used with this ignition. Well, once he found out it was a low voltage issue, he wired things according per perTronix if one has a low voltage issue.... on test drive after that he said he climbed nicely to 5500 rpms and backed off while noting not one misfire.
