Reply to "Has anyone ever made a "Boss 351" pantera?"

DeTom,

yeah, the '71 Boss 351 'stang had the reputation for being the fastest accelerating Mustang "off the show room floor" until the 320 bhp cobra Mustang came along in the '90s. This was not because it was the most powerful Mustang, but because it overwhelmed the stock chassis less than the big block Mustangs, less tire spin equated to more acceleration. The Boss 351 accelerated to 60 mph in 5.8 seconds and pulled the 1/4 mile in 13.8 seconds. The engine was rated at 330 bhp, and the car had a 3.91 rear gear ratio, traction lock & a 4 speed top loader, rolling on F60 x 15 polyglass tires. The engine had a 6100 rpm rev limiter, but Ford issued a bulletin early on explaining how to disable it.

The Pantera could have used the extra 50 bhp of the motor, but what a pain it would have been to adjust the valves about every 6000 miles.

That same year, in Australia, a similar (identical?) motor was installed in the Falcon GT HO phase III one of Australia's most famous muscle cars. It came standard with 3.25 gearing and a 4 speed toploader, did zero to 60 in about 6.4 seconds, the quarter mile in 14.4 seconds and had a top speed of 142 mph (all this from memory, so forgive me if I err). It had the distinction of being the worlds fastest (top speed) 4 door sedan that year. Estimates of the output for that engine are 375 to 400 bhp.

None of my Australian contacts have ever been able to tell me in what way the GT HO phase III motor differed from the Boss 351 motor, if any.
