With the 5th Generation F-100, Ford strived to build a truck that would fit every sort of lifestyle. With more engine choices than you could count and packages like the Contractor Special, Farm and Ranch Special, and The Camper Special, you'd be hard-pressed to find an F-100 that couldn't do what you needed it to. When you add some Holley parts to the mix, the same can be said today whether you're hitting the local cruise-in or the local test 'n tune.
