The rare Mustang was found in a barn after a 46-year-old seat, and it’s a model few people recognize.
The Boss 351 was only available in 1971 and was located under Boss 429. As the name suggests, it has a 351-cubic-inch V8 engine mated to a 4-speed manual transmission that transmits about 330 horsepower and 370 pound-feet of torque to the rear wheels.
The Boss differs from the standard Mustang thanks to a cast iron crankshaft, a high-flow head taken from the earlier Boss 302, and an Autolite 4300-D carburetor designed specifically for this model. The pistons were upgraded to forged aluminum blocks, and the block had four bolts instead of the usual two covers.
In addition to upgrading the engine, the Mustang also received powerful front disc brakes as well as a suspension package for competitions. You needed to be a real boss to fight this oil car, as manual steering was the only option available, but the reclining rear seat and rear window defroster made it a little more comfortable.
Only 1,806 copies of the Boss 351 were released, which is slightly more than the Boss 429.

According to the author’s video Autoarchaeologistthis particular Boss The 351 was acquired by the new owner but has been sitting in the barn since 1976. Originally the first owner ordered the car in red, but when it was delivered, it was clearly yellow. Since he was colorblind, only when his wife told him it was yellow did he find out.
To try to get a little more gas, the owner tried to install a two-cylinder carburetor on the engine instead of a four-barrel unit, but the project was stopped halfway to the end, and the car was shoved into the barn.
The condition is extremely good, but will require a lot of cleaning and removal of the animal litter before you actually take it for rotation. With just 46,175 miles (74,311 km) on the odometer, it is likely that the engine is still in good condition if nothing climbs into the cylinder and dies as a result of open intake.
The Boss 351 is now heading to a new owner who will hopefully return the car to working order.
