MC9 Hyd. Roller Camshaft 1987-97 TPI & LT1/4

219/224 Duration @ .050      .520/.520 Valve Lift    112 LSA A great camshaft for 350 TPI & LT engines. This cam is easy on valvetrain parts and exploits the characteristics of your existing manifold and runner length designs of the long-runner TPI manifold as well as the short-runner, big plenum design on the LT engines.  We've also used this on mild 383 C.I. engines where off-idle-5,000 RPM efficiency is the goal such as a truck or heavier car like the Impala SS etc.  Please let us know what year and engine you have in the "comments" section when ordering.
