I used the Compcams Xtreme energy cam in my previous car and i was so happy with it, that i purchased it again for my new project.

Its a 268/280 cam and is rated to make power between 1600 to 5200 rpm.
Its a good combination of low end torque (Which is good for around town) and high end horsepower. That is why i think it is such a nice cam for street and strip use.
It also has a pretty nice lopey idle. I just love it so much. It sounds good.
Hope thats helpfull.
