@fastestlaps please delete 0-100mph and the 0-100mph-0, they are not realistic estimates. I also dont think this car was tested 0-100kph.

Yeah, you have to remember that, back then, almost anything putting out over 300hp in America was a big block, like the 454 "LS5" engine offered in early 70's Corvettes. So 330hp was pretty damn good for a small block back then. That's why engines like GM's LT-1 and L46, were kind of a big deal at the time.
And it gets more impressive still when you remember that right after the Boss 351, emission standards were tightened in the US, and we ended up with "sports cars" packing horsepower figures that wouldn't even make a BRZ sweat.
So yeah, for 70's small block, 330hp was great.

Finally all the elements came together with the Boss 351 engine. High compression, solid lifters, high flow Cleveland heads, and the cubic inches to make good use of them. Aluminum intake with a decent size carb. Before the Boss 351 came along there was always something missing in the equation. Boss 302 didn't have the cubes to really utilize those heads & valves & carb. So low and mid-range power suffered. The Boss 429 had a rather mild hydraulic cam and under sized carb to take advantage of those hemi heads. Always something was missing. Not saying that those cars weren't awesome performers. They definitely were great cars. But the Boss 351 finally had all the elements to take full advantage of those Cleveland heads. They had the cubic inches, the high compression, proper solid cam, and a good carb/intake combo. Too bad it was only done for one year.

Probably the fastest of the 1st generation of Mustangs (1964-1973), it was a looong time before any Mustang matched this cars performance. Unlike some other cars of 1971, this Boss Mustang wasn't overrated in its claimed horsepower very much. I believe it would be rated at 285 hp net in modern ratings or maybe a bit more. I do know that in 1972 the Mustang Mach 1 with the 351 "Cleveland" engine in a lower compression ratio form (8.6:1) put out 266 hp net at 5400 rpm, and 301 lb/ft of torque at 3600 rpm. So this high compression version may have put out over 300 hp net! Watch the original "Gone in 60 seconds" film by H.B. Halicky (1974) to see what kind of performance and durability these 1971 to 1973 Mustangs had (even though they were using skinny bias ply tires in those days). Very impressive.

This car is poor qaulity bye world standard's their's hardly any traction control the suspension is soft and poor qaulity and still to this day their poor qaulity they should get the clutch gearbox suspension and traction control right before they add any power well i guess it's an allright car most american car's have this problem but I can still understand why peo[ple like this there's alot of charactor to it and people like to modify it and use it for street racing i supose the design's of most american car's are not very smooth but they are classic in historic statues.
