How does the 400 compare with a 383, externally?

If you wanted to build a stroker but keep it looking as close to stock is there any big things that would stand out?

There's one other slight visible difference between the 383 and 400 blocks that a keen eye would be able to pick up on.

Although completely interchangeable, the bellhousing mounting boss differed 383-to-400 blocks.

For example:
