1970 Ford Mustang

1970 Ford Mustang Overview

In 1970, John Naughton, a Ford Motor Company vice president and general manager of the Ford Division, said, “With a more powerful nine-engine lineup, additional muscle-car options and the new colors, the 1970 Mustang comes on stronger and sportier than ever before.” The truth was more subtle. The 1970 saw no major changes to the Mustang lineup. The 1970 Mustang body resembles the 1969 body with the following visual external modifications. Internal modifications consisted of a different steering wheel, new high-back bucket seats and the addition of an optional interior decor group added too. The engine lineup changed slightly for 1970. Total Production for 1970 was 190,727 units.

Background & Details

The 1970 saw no major changes to the Mustang lineup. Most of the changes were in the way of subtle refinements. The 1970 Mustang body was basically the same as the 1969 model year body with the following visual external modifications:

  • The headlights were moved inside the grill opening. The outboard location where the headlights previously were located was covered with a simulated air intake piece.
  • The simulated air intake on the fastback’s rear quarter panel was removed.
  • A reverse facing (simulated scoop was added on the Grande’s side and looks like a backwards comb.
  • Rear tail lights were flat and recessed.
  • A shaker hood was available on all 351 engines and the Boss 302 v-8 engines, but not the 428 CJ
  • The Mach 1 grille was restyled and included 2 driving lights.
  • Hood pins were replaced with twist style locking pins
  • The rear taillight panel got a honeycomb panel
  • The lower Mach 1 sides got an argent metal panel with MACH 1 molded into it.
  • A win-type rear deck air spoiler was also available, along with tinted glass.

On the inside, modifications consisted of a different steering wheel and new high-back bucket seats became standard equipment with the seat back release moved to the lower part of the seat. A new “oval” steering wheel (supposedly to ease entry and exit), and the ignition switch was moved to the steering column which locked the steering wheel when turned to the off position. The 1970 Mustang also featured

molded louvers that protected rear seat passengers from direct sunlight. They were painted a racing black color and hinged upward for easy access to the back window.

There was an optional interior decor group which consisted of simulated wood grain interior, knitted vinyl or high back bucket seats with a blazer stripe. A deluxe steering wheel, and on the exterior: dual color matching rear view mirrors, rocker panel and wheel lip moldings.

The headlights became dual units again instead of the quad units used in ’69, front side marker lamps were moved up onto the fenders, the quarter panel “scoops” were deleted, and the rear taillights were now recessed into their housings.

Engines

The engine lineup changed slightly for 1970. Performance modifications as always depended on your engine and package. V8s with dual exhaust now had 2 mufflers mounted in front of the rear axle.

The 390 was dropped and the 351-2V Cleveland and 351-4V Cleveland replaced the 351 Windsor models of previous years. The 390 engine had become obsolete and the Cleveland units were better all around. The 351 engine package spouting a 4bbl car was only available in the Cleveland variety. There were 351 2bbl engines installed a mustangs if requested. It was the luck of the draw whether you received a Windsor or Cleveland 2bbl engine.

The 428 drag pack was produced with either a 3.91:1 or 4.30:1 axle ratio. The engine received an oil cooler and 427 type connecting rods, a different harmonic balancer & flywheel.

Special Edition Models & Variants

The Grande, Mach 1, Boss 302, and Boss 429 were all available in 1970 and the Shelby cars had their final year. There were several territorial specials like the Twister Special that are hugely popular with collectors today.

The Shelbys

The 1970 Shelby came in two models: the Shelby GT-350 and the Shelby GT-500, in both fastback and convertible body styles. 1970 Shelbys were carry overs from 1969; and therefore the bodystyle and options did not change. One difference was the hood stripes. In 1970 the Shelbys had two black front pointed hood stripes centered over the outer four hood vents. This was the last year the Shelby was offered. It doesn’t appear again until the 2006 model year.

1970 Ford Mustang Sidewinder Special

Sidewinder Special Mustang

Not a lot is known about the ’70 Sidewinder Special. What is known is that all sidewinders were produced with 351-4V engines, were Dearborn built, were all sportsroof models, and were sold in the Oklahoma Sales District. The Sidewinder came in a variety of colors, and sported a decal which was similar to Ford’s own cobra cartoon. These decal stripe kits were placed in the trunk, and were to only be applied by the dealers who decided to be involved in the promotion. It is believed that about 40 Sidewinder Special were produced.
