If shifting at 5500-6000 rpm drops to 2500-3000 rpms power just not gonna be to high there.
Plus hp as a % of torque at that rpm range is 48 to 58 % so 20ibs-ft cam difference is 9.6-11.6 hp difference.
This is “The Rub” I was talking about in gear shift changes.
Luckily, the Purple cam isn’t to bad at that low 2500 rpm. But it could certainly be better. If you could drop 10*’s of intake duration @.050, that would cover it well.
