Our new single plane intake manifold is inspired by the Mopar M1 intake, (arguably) the best intake ever made for a Big Block Mopar. Mopar Performance discontinued the M1 many years ago, leaving us Mopar guys high and dry, and causing what was left of the originals (when you could find them) to fetch upwards of $500 or more on Ebay and at swap meets. These are great for aluminum headed stroker motors (especially with CNC ported heads) that require more airflow than a single plane or even a raised single plane style. And, we've got 'em at a fantastic price!
