    I'm envious! My first truck was an 83 359 with a 400 A model. I loved that truck!

    Looks like a great find. I know absolutely nothing about any if that. Before my time. I had a 92 3406C. Ran 1 mil miles. Only parts ever changed were a waterpump, and finally a fuel pump. Loved that engine. It didn’t pull as good as the full mechanicals like yours. Old timers always warned about the damper. Mine never wobbled. Otherwise it’s Rotella every 10k, and Cat fuel filters only. That’s all I needed to know.
     
    Sons Hero, Last Call and Oxbow Thank this.
