    Great Sound

    this cam has a great sound and crisp throttle response , has a rough idle that turns heads but smooths out when you give it gas. Great cam for old classic cars or trucks , needs a slight stall converter if running automatic but works great with straight drive

    88 Chevy truck thumper

    The cam has a great rough idle. It performs at the RPM's it says it does. With the correct Stahl and gears. It will turn your street machine into a beast! I highly recommend it!
