Cylinder deactivation in high HP V8

[hgprem400]

Guys,
I'm sure this has been attempted many times before however I don't know with what success and application but I'm after some feedback as to whether cylinder deactivation is a sound method to run multiple classes at Bonneville using the same engine.
Assuming the mill is a N/A 496 BBC with around 2hp/ci and no electronics, is there a way to do this without hurting the engine? Appreciate any comments thanks.
