Cam or Driveshaft????

[bigred90gt]

My girlfriend already told me that she would buy me an aluminum driveshaft. I noticed, right after asking her for the driveshaft, that most of the motorsports cams are about the same price. Which would you suggest?

Now, I know that a custom grind is the best choice, but, between the alphabet cams, which one is about the best? I am going to try to get into all types of racing. I would like to do a little road racing, but my main focus is on drag. Also, what would be the max lift you could have and not have to worry about valve to piston clearence issues? I plan to eventually buy the Roush 200 heads if that helps. I was looking at the X or F cam. The only thing that scares me is the lift on the X cam. I also want to get some roller rockers. Which do you suggest. I know it is a lot of questions and kind of lengthy, but all suggestions will be considered and greatly appreciated. Thanks.
