Trick Flow® Track Heat® intake manifolds are precision CNC-machined from A319 aluminum to reduce weight and give your small block Mopar engine more power. The manifold's one-piece spider-type design with extended high-flow runners and raised plenum floor provide significant increases between 3,000 to 7,000 rpm--right where it's needed the most. Trick Flow also provided extra material around the port openings for custom port matching and added bosses that can be drilled for nitrous nozzles. Any 4150-style square bore carburetor bolts up to the Track Heat intake, and with a carburetor mounting pad height of 5.125 in., the manifold should fit under most hoods.
