I'd forgotten (old age will do that) Holman-Moody made a few of these Beasts:
1966 427 SOHC
The Mustang also got a boost in its already high-performance image when Holman-Moody racing ordered 15 1966 Mustangs for use in the A/FX drag racing class. These Mustangs were turned into brutes, thanks to the installation of the 427 SOHC "Cammer" V-8.
The picture of the 1966 Mustang A/FX drag car didn't "paste" but it was a fastback with various stickers...
Wouldn't it be fun to take one of these to the track today!!
