This Boss 351 hasn’t been driven since 1976, which may seem unbelievable. This indicates that the initial owner only utilized it for five years. As a result, with only 46,000 miles (74,029 km) on the odometer, the Mustang is also a classic with low mileage.
Documented by YouTube barn find hunter “Auto Archaeology,” this Boss 351 has been in the family since day one. There’s no info as to why it was retired in a barn so early, but it soldiered on through 46 years of storage in fabulous condition
Sure, it’s all dirty on the outside, but the body and the paint appear to be almost as new. All it needs is a good wash and a nice polish. The interior doesn’t look bad either except for the dirty carpets and the slightly used rear seat. And look, it still has the dealer “Cobra” sticker on the deck lid.
On the flip side, things don’t look as good under the hood. The original, numbers-matching engine is still there, but it’s covered in what appears to be the remains of a rat’s nest. Once all the debris and the rat poop are gone, the 351-cubic-inch (5.8-liter) Cleveland V8 should be there.
The conversion was a response to the oil crisis and the rising gasoline prices. Originally, the 351 V8 was rated 330 horsepower and 370 pound-feet (502 Nm) of torque due to a configuration unique to the Mustang Boss 351. The R-code Mustang remained in production in 1972, but the mill was detuned to 275 horses and 286 pound-feet (388 Nm).
