changing sparkplugs in 440.....uggh

I think it was Snap On that had a ball and socket swivel spark plug socket, that you could add more swivels to. Back in the '80's I did a bunch of tune ups on Big blocks. Most could be done from the top with this socketand a long extension.
Man I don't miss the burns. I also had picked up a set of Kevlar arm bands, and could lay my arm right on the hot manifold and never feel the heat.
Tune ups usually took between 15 and 30 min depending on the car. Sucked working for commission, but it made me better, and faster at it.
