When you have the wrong valvetrain/camshaft in a ford 4 ltr engine this is the result. We now have the cylinder head back together with our custom camshaft and upgraded valvetrain to push the rpm limits of our n/a test engine. With current valvetrain technology (not 1980s valve springs etc) & a custom camshaft grind we have set a goal to push this engine past the 300 rwhp barrier with a factory cylinder head with '0' port work and hydraulic roller camshaft. This will be no dyno queen with amazing torque and horsepower numbers.
