Power limits for LA small blocks?

Just a $.02 addition... According to a book I got "Maximum Boost" by Corky Bell, what kills engines is RPM not cylinder pressure from extra torque. In other words the inertia forces acting on the block, crank, rods etc. from everything spinning at high RPM puts a lot more stress on the parts than the combustion pressure itself. That's why you see a lot of turbo engines making way more power than they ought to be able to handle; the boost allows them to make more torque (and thus power) at a lower RPM range.
