Question Power range?

2005 L33.
Summit cam # 8715
271/287 advertised.
.600/ .575 lift
222/233 at .050.
TFS 2500286 springs.
Manton rods.
Fresh/Stock 799's.
TBSS intake and Late Camaro exh manifolds.
Holley Term Max.
Installed in a 55 Chevy C-dan.
4L60E trans.
Looking for SWAGS on the power curve so I can dial in shift points.
Old timey suggestions say max torque plus 10%.
Y/N?
Input appreciated.
