84 and earlier US are definitely non interference. 300hp and earlier Euro motors are 'sometimes' non interference (meaning you can get lucky).
Yours is 310hp, and is interference.
Make sure you rebuild the tensioner and replace the idler roller. Also a very good idea to change the water pump while you're at it.
