340 stroker build questions

So you don't have to run a bigger (relatively) cam in the 340.

Or the same cam will be made more tame in the stroker with smother more quiet idle and more street friendly.

And the stroker will make the same HP and TQ at lower rpm levels that is less taxing on the valvetrain and less necessary for expensive valvetrain parts.
This is exactly my goal. More horse power and torque at street friendly rpms. This build may end up being more like 475-500 horse I really not sure how much power it will make when done. I'm focusing on building a bullet proof short block for now. I'm planning on edelbrock heads roller cam ect. What should I be doing cam wise? I have -20cc pistons that will be at 0 deck.
