What "makes" a 66 Barracuda a Formula S ??
Thanks.
On the Formula S matter, the October 1965 revision of the Barracuda order code list (form 84-380-8653) says that package 367 is the Formula "S" Package and has the following (which matches the window sticker posted on page 3 of this thread):
FORMULA "S" PACKAGE
(N/A with Group 359 or 368)
Commando 273 8Cyl. 4bbl Engine
Suspension Package-H.D.
Rear Springs, H.D.
Torsion Bars, and
Sway Bar.
Shock Absorbers-Firm
Ride-Front and Rear
Tachometer
6.95 x 14 Special Blue Streak Tires
Heavy Gauge Wide Rim
14" Wheels
14" Wheel Covers-Bolt
on type
Formula "S" Nameplates
That. is. it. Other stuff IS available by other option codes, like the woodgrain wheel, the console, AC, front disc brakes, stripe, (even vinyl roof) etc.
Group 359 is the Sport group with Woodgrain Steering Wheel and 7.00 x 13 with bolt on wheel covers and Group 368 is the Suspension package with HD rear springs, HD torsion bars and the sway bar (but not, interestingly, the Firm Ride Shocks that come with the Formula S package).
I am sure someone has already posted the order codes form, but it's a wealth of info.
