I have a 69 Z that runs pretty sick and I need some help. I've had friends tell me it's only the carb, but I want to make sure. The car runs real rich, but when I had a guy jet it down it ran too lean. I'm not much of an engine person and was wondering does anyone know who would be a good source to do some engine work in the Dallas/Fort Worth area? Especially someone who works with classic cars? Thanks so much for your help!
