After talking to some friends who are SVT engineers, the reason behind the
running the 87 Octane level is that they must meet the CA CARB board
emission, which every year is getting stricter. The engine are detuned to
meet that requirement.
You can easily remodify the chip to run it at 92 level or greater, depending
on the piston compression and Cam durations.

"Stock motors" without head/intake/cam work NO!!! The least amount of octane
the better. Octane slows down combustion, that's why people run it to cure
pinging (i.e. advanced timing ) and high horse motors run it to control
burn. It burns hotter and cleaner (cleaner: why mfgs want at least 87);
hotter: so if you use too much octane when not needed you can burn up O2
sensors and cats, if used repeatedly in high doses.
