Bonneville Landspeed Racing - Let's Try a Thing.

So, now I am being told by a streamliner friend that I should stick with the C500 set up. He has been racing 'liners for 40 years and is very good at aero, but I really can't get my head around it being the better way to go. The hood height drops 8" in current form over the C500 and the radiused side have to be better than the sharp sides. i don't know now.....
