It said in the specs below the video that the cam is: Comp cam 233/276 107LSA. Is that a typo? that is a huge difference in duration. If that isn't a typo what was the reason for such a big difference.
Car sounds badazz!

The small intake duration allows for good low end torque and the large exhaust makes it sound like a 1970 440 six pack car. The tight LSA also adds the sound. Comp makes a "Thumpr" cam grind which is similiar style. Keep in mind, this cam is a driver - it does not make much vacuum at idle therefore there are some trade off's - but I abosolutey love it. This cam requires at least 20 + hours of tuning.
