I raced my dad's truck at the strip about 6 months ago. It is a 2000 chevy Extended cab 5.3 4x4. First run in 2 wheel drive was a 16.9. 2nd run in 4 wheel drive was a 15.8. I think I could've got it down alot lower. He got a K&N cold air kit$250(the stocker is so so restrictive. I think he could bust some 15.5's out of it now. Not too shabby for a 4 wheel drive extended can truck!
