I have a 78 C10 that I just had the engine rebuilt in. I have a 280 comp cam, Edelbrock intake, headers, MSD Ignition and distributor in a 454 big block. I got the engine all back in truck and the number 7 cylinder is getting about 220 degrees. It’s starting to melt the paint before I turn it off. What could be making this thing hot. It’s only hot on the driver side.
