Yeah , that s a running debate.

The 285 engine was produced and killed as it was thought  the supercharger setup would produce more H.P. than a carburated engine.
The blower setup and cam design for the supercharged engine was developed later after the 285 engine was killed

No body really knows what the 285 H.P. cam is as there is no Ford documentation has been unearthed.

Love to find out what the 285 used as a cam.

Old Mics, have I read or heard somewhere that the 285 HP dual quad engine may have used the B7A-C cam?

If the box info is correct then you know both of them are Phase 2 grinds

Again I dont know why 2-4 would be on the box

Measure them to see what you actually have
