Yes, I read about that ahead of time before installing the HEI, and I do have an ignition hot regular copper wire going to the fuse box.
I hope I can get rid of all the ping. Right now it runs great and as long as I don't gun it (at lower RPM) there shouldn't be an issue. I have to figure out how to connect my tranny kick-down to the carb (cable is too long) so low RPM load can be avoided.
Also, this 307 of mine has 283 heads so it has ~9.9:1 compression. I want to try 91 gas to see if that fixes the problem.
