I always figured the 427 higher torque set point was due to the typically higher compression of an original 427? While I did use the 100-105 torque setting, my current engine is only 9.6 to 1 when it USED TO BE 12.5 to 1.

So I was just thinking with the reduced compression, perhaps the 100-105 is a bit over kill for a 427. Original iron heads on mine, by the way.
