I prefer Crane Paul.....I have seen MSD boxes fail on members here so I stayed away from it. Its well known in the antique crowd that MSD boxes do not do well in a harsh environment like under your hood. Most people put them in the interior.
My Superbee has it mounted under the hood and I have never had an issue with it at 12 years old (6AL). I havent had a chance to relocate it.
