434Ci Small Block Engine Build Rocker Arms
|
We went with COMP Cams’ 1.6-ratio Ultra Pro Magnum rocker arms; these gems are built out of 8650 chrome-moly steel and designed with a weblike structure to add strength where it’s needed and reduced mass in low-stress areas. All this helps provide maximum lift and the ultimate valvetrain control in the upper rpm range. View Related Article
