Dude,
Good luck finding Mopar enthusiasts here. The 3 guys you found (including myself) on the Jet Performance page are it.
Mopars are just not very popular in the ***boat world. Fords & Chevys seem to be the rage. Maybe if the Hemi wasn't so costly, and for years out of productio, it would have stayed popular in the racing ranks.
It's probably since the last year the 440 was made was in 78 and most consider it a memory.
