You raise a good question, which I have not been remiss in investigating.
If you look at Google Maps, N Main St. north of the location, is heading due south, but makes a gentle bend to the east, just before it reaches there.
I would imagine that a head-on collision of the ( pesumably southbound ) car with a north bound car ( or other vehicle, ) taking place somewhere on that bend, would be required to create an oblique trajectory to the SSW to hit the wall of the house, which faces due west.
... best I can do! Anyway, an insane collision.
I should mention, that in the news photo of the building, showing the impact damage, you can see that there was apparently some damage to the window at top right, which could be interpreted as the initial contact of a “glancing” blow, which seems to be required by the context.
... well say it was, and say it was an engine block, then that raises the question of where the engine block ended up.
This evidence would indicate that the reaction force of the brick wall to this glancing blow would have deflected the trajectory outward, and the engine block did not “crash through” to the interior of the building, and must have landed on the ground somewhere “down range”.
