Look for a cam with an intake duration in the low 200's (200 to 206) and exhaust duration between 206 and 212 at 0.050". Try to use about 6 more degrees on the exhaust as compared to the intake to help the exhaust flow. Stock exhaust ports and stock exhaust manifolds tend to flow poorly. If you plan to use a carb get a cam with 108 to 110 lsa. efi does better with 112 to 114 lsa.
