I'm goingto say with what you describe , pretty much stock , no it won't . I have a 69 383 4 spd Dart GTS with 3.91's and it wouldn't break them loose on a roll ...
Rev it to 4grand, sidestep the clutch and it's a different story ...
Same here John, well sort of with my '69 GTX 440 4-speed and 3.54 and 255/60-15's on the rear it won't break rear wheels loose on a roll in the dry. Have to figure that the car on a roll has a lot of traction already to move the what nearly two-ton car, so overcoming that traction will take some torque and HP. And with Suregrip that traction is now divided by two or is that multiplied by two? At a dead stop with no tire rotation, it's easy to spin them versus overcoming the moving forward traction already there. Probably do it turning and unweighting the inside tire but difficult going straight.
