Yes indeed.

Not only that but the size of engine was being equated or compared to the build quality of the plane itself.

This is akin to saying that your car doesn't drive down the road very well, because it's blue.

Both may be valid assertions, but they do not influence each other.

e.g. putting in an oversized engine (or not) does not indicate that the model is poorly built.

As Darock stated the .46 pulls like a demon on this thing, due to it's size.

If you go larger, more power to you (litterally!).

But if you rip out the firewall, as a result, bear in mind that this was originally a .30 plane.
