5.0 MOD STROKER PART II
Building a Blown 5.0 DOHC Ford Stroker for the Street

In Part I of this mod motor stroker buildup (Super Rod, Aug. ’08), we documented Injected Engineering’s progress, as well as its techniques, in assembling a 5.0-liter Ford modular DOHC stroker engine. This 300-inch, 32-valve engine will see duty in a street-driven, supercharged Lincoln Mark VIII, a consideration that provides the reasoning behind many of the component choices.
The bottom end is forged to handle the boost, and the extra cubic inches should provide more grunt on the low end (of the rpm scale). The block is the preferred Teksid aluminum piece, which is stronger than the later aluminum blocks. So as not to deprive the Lincoln of sufficient vacuum for the power brakes, the heads and cams are stock ’96-’98 Cobra parts, and in addition to preserving vacuum, they make good power down low, where the car will spend most of its time on the street.
We left off as Injected Engineering’s Eric Carrion began arranging the fairly complex timing chain system. Here, he completes that task, along with the rest of the engine. Among the new pieces introduced in this stage of the build, the most important is likely the ’96-’98 Cobra intake manifold equipped with Intake Manifold Runner Controls (IMRCs), butterfly valves that help give the intake runners two different characteristics—short runners produce torque and long runners produce horsepower. The IMRC arrangement helps one intake produce more of both, though some drag racers favor eliminating these valves for ultimate narrow rpm band power.
Carrion dressed the rest of the engine, adding valve covers, timing chain cover, water pump, oil pan and other necessary items for a functioning powerplant. Once installed in the Lincoln, this stroker motor will be paired with a Vortech S-trim supercharger making approximately 15 pounds of boost—believe it or not, that number isn’t all that wild for a forged mod motor. Modular drag racers have been known to subject their engines to 20 and even 25 psi of boost, so one thing to know going in, these engines are tough. Dyno tuning was not complete at press time, but considering that before this engine was built, the 4,000-pound Lincoln ran 12.16 at 113.4 mph in the quarter-mile, this new engine should produce some truly impressive results, and all with stock heads and cams!
