Fellow boater has that same cam in a Coretti 525hp 496 in his formula. Bullet specd the same duration for another Formula on our home lake with 496's. Seems like a popular choice for mild builds, needs more lift in my opinion though.

If your worried about reversion with a 3/4 race cam, use an RV cam...

My 1982 Mustang GT was advertised by Ford as having a marine grind cam and made a whopping 157 hp. Now it makes about 450, lol.
