From experience I can tell you, a stroker motor cures any deficiencies in low-end or idle that may have been caused by a Vanke intake modification. My 474 Hemi with a Vanke intake torques out like a locomotive and pulls hard over 7000 RPM. that's not to say that there aren't better choices for an intake, like the stage 5, but if you need to use the stock casting, the Vanke mod is a good start
