The engine doesn't care how it's mounted as long as it gets what it needs and doesn't fall off.
The 3.5hp briggs flatties revved their little brains out vertically and took an amazing amount of teenage male speed abuse. Cheap and numerous were the advantages back then. Horizontal shaft motors cost more back in my childhood when everyone had a minibike or gokart. Verticals were boat anchors.
Cheap and numerous; yep. I have a few of them, so I might as well experiment with them.
As for the mount, I plan to cut most of it away. Once I do that, it might just fit into a cruiser frame better than the flat bottom of a horizontal Briggs.
