Anyone able to point me to resources about what exactly is needed to do the 3.7 crank in the 3.5 hr block?

I know the crank drops right in, do I need anything else besides the rods from the 3.7?

I ran 35HR Block + VHR Crank + VHR Rods + 35HR Pistons on my latest build.

So is any actual machine work required for this ? (Of the actual rods / crank / block to accommodate the 3.7)

I plan on ordering a new 3.7 crank, and forged hr pistons and vhr rods.

Dangit Rob haha no additional machine work is needed. Just assemble the HR short as you normally would but with the crank and rods from a 3.7L. Bearing clearances and part numbers are identical. Only the full on stroker kits need clearancing work

Compression Ratio?

You shouldn't since your not changing things that much. A stock ECU with Up rev should handle it.

What is the resulting displacement and what are the pros and cons of this swap?

~3.7L. Its a cheap mans stroker kit.
