I think the 225 Chrysler slant 6 had a 3.5 inch bore and a 4.5 inch stroke.

After some reading, I'm guessing the reason the Slant 6 was a... well,
Slant 6, was so they could make it extremely undersquare to develop a lot of torque at low RPM, efficiently, but also have long enough rods that the rod:stroke ratio wasn't too poor (and thus causing excess friction, and bending rods all the time), yet still fit under the hood?
