408w vs 418w

Right now I have a Ford crate 392w with about 5,000 miles on it.

It comes with a 4.03" bore.

I am thinking about using my Sportsman A351 block and go to a 408w or 418w.

The cylinders should be fine,but if not what is the max safe bore ??
My block would be checked out and machined as needed.

There are a lot of guys with either the 408/410 or 418.
With the bore being the same and the difference being in the rotating assembly (same cost),what makes one choice one over the other ??

What are the pros and cons between the two ???

ANY opinions and feedback would be great.

Thanks
