7. The cam Lykins used is a custom solid roller from Bullet Racing Cams. A solid roller was deemed necessary for the power and rpm this Windsor was going to see, even though there is some maintenance involved (setting lash, etc.). The cam is a fairly stout 0.700/0.690-inch lift with duration at 0.050-inch lift of 260/265. The lobe separation angle comes in at 109-degrees and intake centerline at 107-degrees. Lykins is pointing to a small area that requires additional clearance to accommodate the Jesel belt drive timing cover that is used in this application.
