Mailbag: X303 or E303 — Considering Valve Clearance When Selecting a Ford Cam
Q: I have a 1989 5.0L Mustang, and I recently purchased a Ford Performance X303-grind cam for it. I have some questions concerning valve clearance. Can I run stock pistons with this cam, or will it be necessary to alter the piston to achieve the proper piston valve clearance. How much clearance is recommended with this cam?
