Ford Mustang HO
In 1972, Ford discontinued Boss 351 and Cobra Jet Mustangs, while Shelby models were killed two years prior. However, the performance Mustang buyers had no choice and Ford offered the HO model. HO stood for High Output (via Mustang Specs).
It featured a performance 351 V8 rated at 275 hp, which was high for early ’70s standards. In the end, Ford only made about 60 of these in all three body styles.
