You could try this, and it's probably better if you have these messages stored offline. (A bit quicker)
In Mail, select all the messages you wish to 'export'.
Create a new mail - it doesn't have to have an address.
Click in the main body of the mail (the message section.)
If all your mails are still selected, go to 'Edit > Append Selected Messages'.
This should add your selection to your new mail, though it might take some time with 400 messages.
Now choose to print this mail.
In the print dialogue box at bottom left, you should see a button marked 'PDF'. If you click on this, you'll see an option to 'Save as PDF'
