I have Firecores on my small block, but have a new set of Magnecors to try. My Firecores are a ton long and the boots are huge. Good wires I'm sure, just don't care for the fit.



Wow, that's an old set. One of our originals from longer than 7 years ago, looks like. Haven't used those spark plug boots in a long time. The Pro-Fit sets are longer as to route around the valve covers so guys can lash the valves without taking off the wires. Pro-Fits are for engines with headers. The wire markers moving , must be a new 7mm set. Your Magnum should have 8.5mm wires on it. Markers will not move on them.
