The Weiand X-CELerator single plane intake manifold for 2V headed Ford 351 Clevelands (PN 7516) has been re-tooled. That means the popular Ford intake is now even better looking and higher flowing than ever. A revised runner design smooths airflow while giving the intake an even better appearance. The Weiand 7516 is built to support engines with an operating RPM of 1,500-7,000 RPM with a square-bore carburetor.
