How would you build a 416 Stroker 340?

Yes, your manifold will work on this combo. Keep in mind that your powerband will be in the 1500-6500 RPM range.

Yes, that's right about where I want my power band to be as a street car. Mainly, the only reason I don't go above 5500rpm is that I'm afraid of breaking something with this currently weird and partially unknown combination of parts.
