1970 Ford Mustang

The designers of the 1970 stock model Mustang took a step back from the aggressive, hardened look of the 1969 model. The new standard Mustang reverted back to single headlights moved to the inside of the grille opening. Other aspects of the exterior styling were simplified. Rear fender air scoops were removed and the tail-light panels were made flat as opposed to the concave on the ‘69 models. The interior on the standard ‘70 model remained mostly unchanged. 

The 1970 model year saw the previous 351W V8 engine options replaced with a new 351 cu in (5.8 L) Cleveland (351C) V8 in either 2V (2-venturi carburetor) or 4V (4-venturi carburetor) versions. Though some early 1970 mustangs, built in 1969, had the 351W. The 351C 4V (M code) engine featured 11.0:1 compression and produced 300 bhp (224 kW; 304 PS) at 5400 rpm. This new performance engine incorporated elements learned from the Ford 385 series engine and the Boss 302, particularly the poly-angle combustion chambers with canted valves and the thin-wall casting technology. On the inside, high back buckets 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 "Mach 1" was designed as an "in-between" model between the standard Mustangs and the racing-oriented Boss 302's. Both came equipped with the "Shaker hood", the distinctive air intake scoop mounted on top of the hood.
