If your staying with the stock 3.750” stroke of the 400 then the -4s are the only way to go if your working only with 6X castings.

If your contemplating stuffing in a longer stroke crank to gain more cid then there may come a time where the -8s make more sense to avoid having to go for a dished piston.
That’s the bottom line.
