Red hot headers

Thanks for the responses, guys. Since the car has been sitting for many years, it makes sense to me that the carb might be clogged and thus running lean. Makes more sense to me than the timing being off, but we will be checking this of course. The headers go to dump tubes, so I don't think there's any restrictions in the exhaust! We'll tear down the carb and give it a good cleaning. Seeing the red headers gave me quite a start, and I said, "I know where to ask a bunch of people that know way more about it than me!" Thanks, FABO. (Secret: it's a '71 Charger, so technically it ain't no A-body! But now it's in the driveway right next to my '71 Dart, so I hope that cuts me some slack.)
