Kallen, I thought you had previously seen the light and planned to buy a GU, didn't you write the question below?

(What's an acceptable amount of k's on a 3ltr gu
Just looking atm...
But a lot around the 300,000k mark. A few good ones around the 180000k mark. Is 300 sorta mid age for the 3ltr, or pushing the end of it..)
