Steve,
What set up do you currently have? Is it the standard 100-Six cam with twin 1 3/4 inch carbs? If so then you should notice a nice improvement with the DWR 'mild cam'. On the other hand I had the DWR8 cam with twin 2 inch carbs and found that to be a terrific combination for a fast road set up.
The DWR8 is very good at keeping low end torque. Its good from about 1200 revs, with a flat torque curve. The DWR2 rally cam is not so good at the low end but delivers more power higher up..
