408 stroker 8-71 blower e85...teach me

How do you plan in keeping this engine together with 700-1000 HP? A SBM will have a limited lifespan at those power levels. Maybe an R3 or aftermarket block will last...

The amount of boost is controlled by the size if the pulleys not the rotor size.

Built to last you will be well into five figures with that HP ....
