Install the Fords extender and shift at 8500

Be sure to post some pics of whats left of the engine.

Seriously, the stock engine doesn't make any power over 5k so there is no point in shifting any later. If you had a big enough cylinder head to make power up that high, you would need some SERIOUS components to live in the high rpm and power level.

Also, if your supercharger is centrifical, then spinning it faster will give you more boost as long as it can flow that amount or air. You can spin it faster by changing the drive pulley. Just be sure to not overspin it past its efficency or max rpm.
