How about this one?

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

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

John - "The Hoosier Hurricane"

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.

Below is the CAM - 6250 excerpt from the period MPC - REVISED FEB 1961 -CHANGE (page) No.1

Maybe will help someway -

That is the listing for the EDB - E cam which is the 2nd version blower stick.  
Unfortunatly nothing about the 285 bumpstick has ever surfaced

The 285 H.P. engine may have been killed when the Supecharger kit came on stream... but then if I recall correctly, Nascar at some point killled the Supercharger!.  So, whose to say Ford didn't bring it back on, possible complete with that Cam?..

That reference was to validate the EDB-E being released also as a SERVICE PART.

One would need a first issue period MPC to see if a separate cam was issued for the 270HP. The 285 HP cam most likely would not have been a service part but part of the 285HP crate release. Possibly a PRODUCT SERVICE LETTER would have announced it and gave assembly parts?
