Over the weekend, I had an issue where I had lost a cylinder. Through some fiddling around (and mostly luck) the issue resolved itself and was most likely dirt in the idle circuit of one barrel. During my process of elimination, I purchased an infrared thermometer to identify which cylinder was misfiring by taking the temps of the header at each cylinder. After the engine cleared itself out, I took the temps of all eight header pipes and was surprised by the disparity. On the driver side, temps of the front and rear cylinder were about 30 degrees cooler than the center two. On the passenger side, all four header pipes were within 10 degrees of each other and 50 degrees warmer than the hottest pipes on the driver side. This was after about 20 minutes of driving that included highway speed followed by in-town driving, without shutting down engine. This makes me believe the carbs probably have very different A/FRs. I just acquired the car two weeks ago and have only put 200 miles on it. The previous owner stated he spent a small fortune having the carbs set up. The engine runs smooth, pulls very hard but with such low seat time, I couldn't possibly know if I'm missing out on some significant performance gains. Any suggestions?
