Just realized the old guy at the gas station in Amarillo was right about my 289's timing
I always set it by ear because that's what my uncle did, but this stranger heard it idling at the pump and told me I was 6 degrees off. He pulled a wrench out of his trunk and we messed with it right there for 10 minutes, and the car has never run better. Now I'm wondering what else I've been doing wrong just because it's what I grew up doing?
