Stroker it is making changes to the internals of the engine to get a larger cubic inch. For example to make a 347 stroker out a 302 you do a 30 over bore on the block then you do a 289 crank and the 289 shorter rods buy making the cylinder larger then shorting the rod length you get more cubic in and lighter rotating mass so you get quicker rpm and more hp and torque with the larger cubic inch. The stroke it best measured with rod length, center to center. I hope this helps
