Thanks, I've got my timing adjusted where it needs to be and I know I need to be running higher than 93 in my car, '68 Charger w/440, I just didn't know if the slight pinging when getting into it would affect how hard it pulled or not until I asked you guys. I do plan on fixing it by mixing some higher octane Sunoco gas into it but was just curious the results I'd expect by fixing the pinging problem. The car is put away in my garage now for the winter, so I wouldn't know until the spring, but I was to impatient to wait to know so I asked you guys because you all know your stuff.
