I seriously doubt a 250 straight 6 could develop that kind of torque. The 6.5 diesel V-8 in my SUBURBAN was factory rated at around 380-390 ft lbs of torque, and that's a V-8 diesel. The 255HP 5.7L VORTEC truck motors made 330 ft lbs of peak torque. I would say that 165HP straight 6 probably produces peak torque close to the peak HP number, that's normally a good rule of thumb.
