Trick Flow PowerPort 240 Cylinder Heads for Big Block Mopar

Trick Flow PowerPort® 240 Cylinder Heads for Big Block Mopar

Trick Flow has taken its high performance act to the Mopar scene.

Well known for its Ford and GM cylinder heads, Trick Flow has now designed a set of high-flowing heads for Chrsyler’s B and RB engines. When dyno-tested on a 10.4:1 compression, 446-cubic-inch Mopar, these heads made 620 horsepower at 6,200 rpm and 570 ft.-lbs. of torque at 5,000 rpm.

That’s the kind of performance we’ve come to expect from Trick Flow Specialties.

The PowerPort 240 heads feature fully profiled 78cc combustion chambers and CNC Street Ported 240cc intake/74cc exhaust runners for balanced airflow from runner to runner. Trick Flow engineers fixed the shortcomings of the factory head design by relocating the oil holes for the rocker shafts and optimizing the shape of the runners to increase airflow velocity and add much needed strength to the rocker arms’ shaft bosses.

The PowerPort 240 heads are available with your choice of three valve spring packages:
• 1.460-inch dual springs rated to .650-inch of valve lift
• 1.500-inch dual springs rated to .680-inch of valve lift
• 1.560-inch dual springs rated to .700-inch of valve lift

Trick Flow PowerPort 240 Cylinder Heads are machined to clear 3/8-inch pushrods and accommodate all factory-style big block pistons, roller rocker arms, intake manifolds, and headers. The heads are fully assembled with valves, valve springs, seals, locks and retainers.
