First off, I have a M-22 on a '68 400. Last night I took my car out to do some errands. As I was backing out of a parking spot, I smelled an intense burning smell inside the passenger compartment. When I put it into 1st and started to drive, the smell wasn't as prevalent and pretty muched stopped. I've had the car for about six months now and usually when I shift for a stationary position, there is a slight smell, but last night was the worst. Any ideas?
