Ford's decade of "Total Performance" was
drawing to a close.
The Mustang grew by 2.1" of length, 2.8" of width, 1" of
wheelbase, and about 100 lbs. Coupled with this weight
gain was the disappearance of the Shelby models and the
Boss 302 and Boss 429 models, and the weakening of the
remaining engine choices.
The 351 engine was detuned from
300 bhp to 285bhp while the 429 Cobra Jet dropped 5bhp
to 370bhp. The performance banner was carried by the
Mach 1 Mustang and the new Boss 351 model.
The standard engine for the Mach 1 was the 351 Cleveland V8 with 285bhp
but a 330bhp version was also available.
The 429 Cobra Jet sported 370bhp while the top power choice was was
the 429 Super Cobra Jet Ram Air. It had 11.3:1 compression,
and generated 375bhp but its 1/4 mile times were slower
than the Boss 351.
The Boss 351 enjoyed a lower weight
and a race bred 351 engine that had a radical solid-lifter
cam, 11.0:1 compression, ram-air induction and came with
a Hurst four-speed transmission
and 3.91:1 Traction-Lok
This would be its only season as Ford performance
would continue to decrease.
