    Big news from KOS... diesel motorspots going to see big changes.

    The King of the Streets competition just announced today that all trucks must be emmisions compliant to compete. I have a feeling this will become a trend for all street driven trucks.

    The time has finally come to put my 4x4 back together. It was totaled in an accident almost 7 years ago, and unfortunately has been sitting ever since. I had originally purchased a 78 k20 with a 350 combo and 203 case when I was 23. I quickly added a small lift and upgrade the engine with a few...
