with a stroker, you get streetability. peak HP potential is dictated by head potential. stroke will move the power peak up/down the rev range. do a stroker with your heads, good headers, and intake carb combo and a hughes 3038/3844ish sized cam (I'd use 1.6 rockers) and you're looking at something that should idle below 1000 RPM with 12+ inches of vacuum, and will peak out in power around 6500 rpm.

use the same combo with a stock stroke 340, you'll make about the same peak power, but it will be alot higher in the rev range without the low end torque, and it won't idle near as good, you'll need more gear/convertor.
