Dynamic 3D Block
Dynamic blocks are designed for 2D only, point.
Sometimes we can outwit AutoCAD. But before we must know what you want to achieve. "Stretch" - in which direction. Show us an example how the block should look after stretching.

I recreated the block with a fully constrained sketch.

The idea is that it works in a similar way to this 3D block. This is a block of a rectangular solid that you can stretch.
In this one I had no problem doing it, but in this one the problem is the curves.
For demonstrating I use the block which was posted by @Ed__Jobe .

You have to constrain the curves so that they can only vary by their center point. Plus, in your original one, you didn't use curves to define the edges. You used a polyline with a lot of points.

I edited it so that you can adjust the Length, Height and Thickness in the Custom Properties panel. Select it to edit the properties.

Attached a completely other strategy to drive the dimensions of the Base- (2D) Sketch, here using constraints.
At the block References test_1 you can change beside the Length and Height also the Thickness as shown by @Ed__Jobe and additional the Radius of the arcs too (both in the properties panel).
But that has nothing to do with the main question, how to manipulate 3D objects in Dynamic Blocks. I did that only for fun and to demonstrate the power of dynamic blocks with Parametric constraints, even if the practical use of such dynamic 3D blocks is very limited.
Have fun while testing ...

What is your question? At which point do you have problems?
If you're completely new in using constraints (and if your question is related to this) I'd suggest to start a new thread.
