what would cause three plugs on a mild 350 to foul out on the same side of the motor it has new super coil, good wires and good connections, the rest of the plugs are a rusty brown color. the ones that fouled , look like they have been soaked in gas

i would first check to see if your are even getting spark to those three plugs. pull 1 plug at a time, plug it into the spark plug wire and ground it to the block or frame have someone crank the key and check for spark repeat the process on the others . you could have a bad cap or rotor also check the gap
