The two-stage curve is, IMO, the key to making a hi-compression manual-trans combo, come alive. It allows for modest Idle-Timing, running to the target at stall, and then slowing down to prevent detonation after stall, yet still advancing to the limit for your gas, after; in the range of 3000 to 3600. That is how I have been able to run 87E10 at up to 195psi with alloy heads. The 360 has so much torque, that if there is a power lag from my hinge-point of 2800, to 3400, I have never felt it.
