Intake Manifold, 4 BBL, 390-428CJ FE

For All 390-428 FE big blocks w/low or Cobra Jet heads.  Another beautiful intake recreated by Blue Thunder Products.  This is an exact copy of the original Ford Medium Riser 427-428 Interceptor dual plane manifold.  Like all Blue Thunder reproductions, this manifold offers greatly improved flow characteristics over the original; while it resembles the original 60’s Ford item, it will outperform its older counterpart by a wide margin.  This is a direct bolt-on replacement for your 428 Cobra Jet or 390 cu. in. engine.  Delivers excellent performance throughout the entire RPM range, all the way to the very top end.
