NEW 480 Billet CAMS!!
No exchange

Predator 480 Cams

12.19 mm lift - 266° Duration at .050 lift. They are designed for a wide power band peaking from 9,750 to 10750 RPM depending on cam timing and intake length. They have 6 different timing positions that are field adjustable. After the initial installation, you can retime these cams without the use of a degree wheel or indicator. These billet cams are built from special process case hardened steel, and will give excellent service life.
Cams require the use of HPD valve springs with thicker spring seats produced after 1-07, and HPD valve buckets.
Proud to be made in the USA.

Warning: May not clear head or cover castings. Grinding may be required. Initial degreeing suggested! Engines running over 10,000 rpm require crank work!
