170 stroker turbo build

I'm thinking about building a 170/198 engine, myself. But my reasoning is, in the slant six racing series, running the low deck engine puts the vehicle in the next lower class. In other words, if my car fell in "C" Nitrous with a 225 or 198 raised deck engine, it would fall into "D" Nitrous with a 170 engine or a 170 stroked to 198 cubes, with no weight change. Other then for that reason, to me, it makes no sense to spend the time and money to build a 170/198 stroker.
