500 Horsepower Ford Stroker Holley Carb
With a big heads and cam, a single-plane intake is the only logical choice, and Duttweiler's choice for this engine was an Edelbrock Victor Jr. He also tried both a 750-cfm Holley (shown) and a larger 850-cfm HP version. Overall, the 750 HP Holley offers a better power curve even though the 850 made more peak horsepower.

500 Horsepower Ford Stroker Carb Spacer
Experimenting with one of Wilson Manifold's trick 1-inch aluminum four-hole tapered spacers that improved mixture distribution and power. The spacer under the 750-cfm Holley was worth as much as 11 lb-ft of torque at 4,600 rpm while improving power throughout the entire power band.

500 Horsepower Ford Stroker Distributor Plug Wires
Given all this power potential, we had to ensure we didn't lose power to a weak ignition, so Duttweiler went with an MSD Billet distributor and MSD-6AL box to light the fire along with a set of MSD spiral-core plug wires.

500 Horsepower Ford Stroker Engine
On the dyno, Duttweiler also used a Moroso Fox-body Mustang style pan and pickup to simulate an engine in a later-model Mustang along with a set of Hooker headers. Keep in mind that the raised exhaust port on these heads may present header fitment problems.
