Just swapped out my old 305 with a new 350. Problem is, the spark plugs are right up against my JTR headers and it's causing the plugs to heat up and arc. The car runs perfectly when cold, but once those plugs heat up, the engine takes a major hit in power. I have these insulator boots, but they don't seem to do that job.
How do you guys route your spark plug wires and how do you deal with heat coming from the headers?
