Previously we brought you the details on the 408ci stroker bottom end of our true Ford Cleveland build in our February issue, but in this second installment you'll see the magic that will make it a fire breather fit for any fast Ford.

The real stars of this show are the new Trick Flow Specialties PowerPort 225cc Cleveland heads and Track Heat intake. The heads are a big breakthrough, but they aren't a ground-up redesign—they weren't intended to be. What they are is a very thorough revision of the Cleveland architecture that takes into account modern cylinder head chamber and port design gleaned from Trick Flow's extensive racing background and integrates that into in a package that will bolt right onto any Cleveland (or Windsor, with minor mods) Ford small-block, work with other stock-style parts, and create a much improved peak and average power curves.

Also available in 195cc versions, the heads feature intake and exhaust runners based on the low-rpm friendly OE Ford 2V design, but the exhaust runners are raised .100-inch from the OE 2V location to improve the short-turn radius, resulting in dramatically improved exhaust flow. The combustion chambers are fully CNC-profiled and bowl-blended to further maximize performance. In the lubrication department, the oil return system on the Trick Flow heads has been revised to improve oil drainback and also includes provisions for easily mating them with 351 Windsor blocks.

While we're quite sure the FoMoCo muscle car crowd with cars originally powered by Clevelands will be the core base drooling over these heads, it's definitely worth noting that the PowerPort heads also fit 351M, and 400 engines out of the box. That means a new lease on life for a plethora of 1970s cars, and boatloads of trucks. With minor machining and some Ford blue paint, the heads can even be used with 302 and 351W blocks to create "replica" Boss 302 or 351 engines that pack a bigger punch. Let that sink in and stir your imagination a bit.

Enough bench racing, check out exactly what is possible with a very simple and street-oriented Cleveland engine built from a bevy of well-chosen parts sourced exclusively from Trick Flow and Summit Racing by a knowledgeable shop like Ford Performance Solutions.

  • Cleveland 408Ci Short Block
    Four years isn’t much time for an engine to hang around in production, but the legacy of the 351 Cleveland has been felt throughout hot rodding and motorsports in the nearly four decades since the last one was produced stateside.
