Newbie-ish engine question. I should know this.

I re-angled my exhaust a couple of months ago, and pointed them upwards a little bit. Last night, I noticed that the ends of my bumper, by the outlets, had soot on them. Is this a sign that I am running too rich?

I'm running a 355, carbureted, with dual exhaust, no crossover pipe.

Not necesarily so. Modern fuels do leave a very black deposit even when the vehicle is running clean.

No biggee, now if you're blowing black smoke out the pipes that's a different story

The only time it blows black smoke is when the secondary butterflies open up, so I'll just assume that I have it right, and not mess with it. Thanks for your help!
