Here is the big difference between strokers and standard stroke small blocks... Streetability. You can put a larger cam profile in a stroker and still have good idle and vacuum. My 240/246 .507/.510 lift cam is fairly mild in my stroker. Remember the increased stroke eats some of the cam duration.

The 238/246 .548/.558 retrofit roller cam in the stroker built for my brother's car is just as mild and a bit more powerful.

You put cams like these in a standard stroke small block and they will not make as much horsepower or torque as the stroker and the idle will be far less streetable, and in some people eyes they wouldn't be streetable at all. These are what I consider the starting point for strokers while they are about as much as you can put in a standard stroke street smallblock. I don't think they start getting lumpy until the 250@.050 range and that should be pushing you over .600" lift...
