1967-1972 Ford F-100 Bumpside Guide

The 1967-1972 Ford F-100 is commonly called the Bumpside because of the convex character line that runs along the body. “Bumpside” is an enthusiast nickname, not Ford’s formal model name.

This fifth-generation F-100 paired a new cab and body with 115- and 131-inch regular-cab pickup wheelbases, 6½- and 8-foot Styleside boxes, and a year-changing selection of six-cylinder, Windsor, and FE engines.

Bumpside F-100 at a Glance

Item	F-100 detail
Model years	1967-1972
Generation	Fifth
Cab	Regular cab
Short wheelbase	115 inches
Long wheelbase	131 inches
Styleside boxes	6½ feet and 8 feet
Front suspension	Twin-I-Beam on 2WD; separate solid-axle layout on 4WD
Successor	1973-1979 Dentside F-100

The SuperCab did not arrive until 1974, so an extended-cab truck is not a factory Bumpside F-100 body configuration.

How to Identify 1967-1972 Bumpside Years

Grilles, parking lamps, side markers, and trim help narrow the model year. Finish details can change with trim or production timing, so use the warranty tag and year-specific parts before treating one visual feature as conclusive.

Model year	Identification and product changes
1967	New cab and body; rectangular grille with parking lamps below the headlamps; Ranger promoted as the top-line Styleside treatment
1968	Revised grille and federally required side reflectors or markers; 360 and 390 FE engines replace the 352 in the F-100 range
1969	Grille related to 1968 with finish and trim differences; 302 Windsor V8 joins the range
1970	Grid-pattern grille, wraparound front parking lamps, revised rear side markers, and Ranger XLT at the top of the trim range
1971	Grille divided into six rectangular sections on each side; revised two-spoke steering-wheel and horn-bar treatment
1972	Grille divided into four rectangular sections on each side; final Bumpside model year

For identification beyond the grille, compare the warranty tag, body code, engine code, axle code, and transmission code with the exact model year. The data plate decoder can help organize those fields.

1967-1972 F-100 Engine Chart

This table is scoped to the F-100, not every F-Series truck shown in a combined brochure. Availability can still depend on 2WD or 4WD, regular-cab configuration, transmission, emissions market, or other ordering requirements.

Engine	1967	1968	1969	1970	1971	1972	Application notes
240 cu in inline-six	Yes	Yes	Yes	Yes	Yes	Yes	Standard F-100 engine
300 cu in inline-six	Yes	Yes	Yes	Yes	Yes	No in F-100 table	Optional through 1971; its 1972 listing belongs to heavier series
352 cu in FE V8	Yes	No	No	No	No	No	1967 only in this generation
360 cu in FE V8	No	Yes	Yes	Yes	Yes	Yes	Replaced the 352 in the 1968 range
390 cu in FE V8	No	Yes*	Yes*	Yes*	Yes*	Yes*	Availability depends on drivetrain and application; verify exact-year brochure footnotes
302 cu in Windsor V8	No	No	Yes*	Yes*	Yes*	Yes*	Regular-cab and 2WD qualifications apply

The 240 was the standard F-100 engine across the generation. The 352 was a 1967-only choice in this body, while the 360 and 390 arrived for 1968. The 302 joined for 1969.

The 1972 F-100 brochure table does not list the 300 Six even though that engine appears elsewhere in the broader F-Series range. That is why an F-Series-wide engine-code list should not be treated as an F-100 option sheet.

Gross vs. Net Horsepower

Ford advertised the 1967 engines at 150 gross horsepower for the 240, 170 gross horsepower for the 300, and 208 gross horsepower for the 352. The 1968-1971 figures also use the SAE gross basis.

For 1972, advertised output changed to SAE net. A lower 1972 number does not by itself show an equivalent year-over-year loss because the measurement method changed. Always label the rating basis when comparing Bumpside engines.

Ranger, Ranger XLT, and Other Trims

Trim names and equipment changed during the six-year run:

• 1967 Ranger: premium or top-line Styleside treatment for the launch year.
• 1970 Ranger XLT: becomes the top trim in the reorganized range.
• Custom Cab, Sport Custom, and Ranger: meanings and relative positions vary by model year.

Badges and replacement interior pieces are not enough to authenticate a trim package. Check the body and trim fields, DSO information, surviving build documents, and year-correct interior and exterior equipment before paying a premium for a claimed Ranger or Ranger XLT.

Air Conditioning, Brakes, and Steering

The 1967 pickup brochure describes its air conditioner as dealer installed. Do not assume that every under-dash unit is factory installed, or that the same installation status applies unchanged through 1972.

Brake claims also need F-100-specific scope. The 1972 pickup specification lists power drum brakes for the F-100 while assigning power front disc brakes to F-250 and F-350 applications. A statement that all Bumpside F-100s offered power front discs from 1968 imports heavier-series equipment into the half-ton guide.

When evaluating a truck, distinguish:

• F-100 from F-250 or F-350;
• 2WD Twin-I-Beam from a 4WD solid front axle;
• drum or disc brake type from power assist;
• original equipment from later conversions.

If a Bumpside now has front discs, identify the exact components and installation instead of assuming they were factory fitted.

Buying and Inspection Checklist

Use the truck’s configuration—not the generation nickname—as the basis for inspection:

1. Confirm the VIN and warranty tag agree with the model year and F-100 series.
2. Identify 2WD or 4WD before ordering steering, suspension, brake, or engine-fitment parts.
3. Verify the engine family from physical features and codes; a 352, 360, 390, and 302 do not share one parts strategy.
4. Inspect the cab mounts, cowl, drip rails, floors, bedside structure, and radiator support for corrosion or previous repair.
5. Check Twin-I-Beam bushings, steering joints, wheel bearings, and alignment on 2WD trucks; use the correct solid-axle checklist for 4WD.
6. Confirm the brake system has matching front, rear, hydraulic, wheel, and tire components.
7. Treat Ranger or Ranger XLT badges as a lead, then verify the original trim with documentation and year-correct details.
8. Compare current market value with recent sold examples that match cab, bed, drivetrain, trim, condition, and documentation.

Frequently Asked Questions

What years are Bumpside Ford F-100s?

Bumpside Ford F-100s are the 1967, 1968, 1969, 1970, 1971, and 1972 model years. The nickname refers to the raised, convex character line along the body side.

What engines came in a 1967-1972 Ford F-100?

The F-100 range included the 240 inline-six throughout, the 300 Six through 1971, the 352 FE for 1967, 360 and 390 FE V8s from 1968, and the 302 Windsor from 1969. Exact availability can depend on drivetrain, transmission, cab, and market.

Did Bumpside F-100s have factory front disc brakes?

Do not apply a generation-wide front-disc claim. The 1972 F-100 specification lists power drum brakes, while power front discs are listed for heavier F-Series applications. Any truck with discs should be checked for its exact model-year equipment or a later conversion.

Did a 1967 F-100 have factory air conditioning?

The 1967 pickup brochure lists the air-conditioning unit as dealer installed. The presence of an under-dash unit alone does not prove factory installation, and later model years need their own equipment verification.

What wheelbase is a Bumpside F-100?

Regular-cab F-100 pickups used a 115-inch wheelbase for the short configuration and a 131-inch wheelbase for the long configuration.

Is a 1972 Ford F-100 less powerful than a 1971?

The advertised numbers cannot be compared directly without adjustment. Ford used SAE gross horsepower through 1971 and SAE net horsepower for 1972, so part of the apparent change comes from the rating method.
