Not sure if anywhere in this mess it was communicated that a 500 CI stroker will eat duration. The cam that might have a 3400- 6500 operating range in a 440, might drop maybe by 1000rpm in a 500 CI.

Nick, the marketing guys for the cam companies list the same operating range for a cam in a 383-500 CI, it doesn't work like that.

The cam in my 520 I think was rated from 3500-7000 rpm.
It pulls down to 1800 just fine, and like any other vehicle, when you learn to drive it, can be done efficiently.

When you have big cubes,you will have more torque than you need.
