Hey Gang! Need some help. Finally got my car all put back together after 6+ months of some upgrades. I put fenton headers with the stock intake and a dual exhaust. I also upgraded the carb from a 1b to 2b from tom landon. I'm getting smoke from one side of the exhaust and it's spitting out black sut. It also sounds louder on the side that's smoking. When I took it on the highway it smokes when I accelerate on the gas and the smoke goes on and off but steady. Where do I start and what could this be?
