The 351-W bock can only handle a 3.5 inch stroke in "standard/factory" form, anything more, one has to notch the bottom of the cylinders for rod clearance, much the same with a factory 302 block.
Your 408 should have a 4 inch stroke, so notching the cylinders is a must, regardless of what type or brand of connecting rod used....
