Trick Flow PowerPort 175 Cylinder Heads for Ford 390-428 Now Available at Summit Racing

Trick Flow made its name helping Ford enthusiasts get more power out of their small block, 351 Cleveland, Modular, 429/460, and even flathead V8 engines. Now you can get Trick Flow horsepower for your 390-428 FE engine with a set of PowerPort® 175 cylinder heads.

Andy Finkbeiner of AR Engineering did. He built an 11:1 compression 482 cubic inch FE with one of the first pairs of PowerPort 175 cylinder heads and made 704 horsepower at 6,300 RPM on the dyno. Check out the story at HotRod.com and this YouTube video of the 482 on the dyno.

The PowerPort 175 heads are direct bolt-ons for all 1961-76 FE engines. The 175cc intake runners have been optimized to increase port velocity, while Trick Flow’s special CNC Ported treatment guarantees proper dimensional accuracy and balance between the cylinders.

And do these cylinder heads flow air—the PowerPort 175s flow 317 cfm intake/239 cfm exhaust at .500 inches of valve lift, and an impressive 338 cfm intake/249 cfm exhaust at .700 inches of valve lift.

Trick Flow PowerPort 175 cylinder heads come fully assembled with stainless steel valves;
Trick Flow by PAC Racing valve springs; 7° or 10° steel valve stem locks; and chromoly or titanium retainers.

Trick Flow also offers a matching intake manifold for the PowerPort 175 heads. The Track Heat® single plane manifold features a high-rise, one-piece spider-type design with high flow extended runners and a raised plenum floor to significantly increase horsepower and torque in the 4,000-7,500 RPM range. The Track Heat manifold accepts Holley 4150 and other square bore-style carburetors, has bosses for nitrous nozzles, and extra material for custom port work.
