440 timing pinging and popping thru exaust
You don't need a digital timing light or timing tapes using a hillbilly timing tape. It uses the std 10-0-10 marks as well. Good god damn that's convenient! Some people like to save money, count me in. Been timing cars with a 30 year old inductive timing light and HTT method, no fancy or sometimes finicky electronics required.
Good luck with it.
