No, not a stroker. Shifted above 6k RPM but not like what you are doing. Where the engine makes torque/power is heavily dominated by the cam choice; what you chose is definitely a high RPM cam. But the inherent low RPM torque of a stroker, and with that DCR, it would be expected to start the 'usable torque' band at a lower RPM. IMHO, the heads, even ported, are going to be the thing that stops the upper end of the RPM band before that cam stops; that engine is gonna want a lot of air.
The upper RPM range is quite variable and depends on so many things (strength of rods, rod bolts, crank, pistons, valve train parts), and as I never have built your combo, I could make only a pure guess that would have no useful meaning. I would be a lot better to ask those who have built combo's like yours on that, and list the parts you plan to use in detail. (And, don't hold anyone to their opinions, as they won't control the build.)
