After tuning, the Dart-headed stroker produced hp at 6, rpm and lb-ft of torque at 5, rpm.

The multiple-layer steel construction allows the dynoo to conform to movement between the cylinder head and block while maintaining a good seal. Edelbrock E-Force on an S Coyote!

The engine never huffed oil out of the breathers, and the spark plugs all looked excellent. Equipped on the dyno and ttests to perfection, the 5. The Dart heads were capable of supporting a great deal more power, but the limitation was the displacement, cam timing, and intake manifold.


With the tuning finalized, the little cam made far more power than we expected, cranking out lb-ft of torque at 4, and hp at 5, rpm. The rest went very smoothly, and we reused the stock lifters and suffered no ulcers worrying about breaking in the cam. Late-model hydraulic roller 5. We have included the horsepower and torque graphs for a bone-stock 5.

The heads also required some machine work, including screw-in studs, gests, and widening the spring pockets for bigger valvesprings. We we set the timing to 34 degrees and rejetted the carburetor to get our desired By subscribing you agree to the terms and conditions of our terms of use.

For the stroker, we stepped up to a larger Crane hydraulic-roller cam. How about which mass air meter yields the biggest gain? We apologize for this inconvenience and encourage you to visit www.

The longer duration created a slight loss of torque below 3, rpm compared to both previous cams, but beyond that mild loss of power, the bigger Voodo out-powered its smaller cousin, cranking out a peak torque of lb-ft at 4, a gain of 7 lb-ft over Test 2 and charging to a peak horsepower of at 6, rpm.


We pulled this hydraulic roller-cammed 5.

Make 503HP With A $350 Junkyard 302

The same can be said of hp combos making hp and hp motors that make nowhere near hp. Displacement ci Bore 4. Fuel flow came courtesy gord a complete Aeromotive fuel system.

These cast piston short-blocks are not quite as good as the forged piston 5. Perhaps even more surprising was how well this engine idled, calmly purring with 16 inches of manifold vacuum at rpm.

Some ideas never go out of style.

This test went so well that we were eager to see what the slightly bigger cam would do. We also added a veteran Ford magnetic pickup distributor and used it to drive an MSD ignition system.
