Archer used to also race Jeeps in the 80's. A friend of mine from high school was a parts runner for them around 1990 and he was usually driving a red Comanche that was quick as hell. I'm guessing all their speed parts are for the 4.0L inline 6 that Jeep used for years. It's a bullet proof motor, but the factory exhaust mani's cracked all the time, so that header would be a nice upgrade for most Jeeps.
