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?

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.

KT 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?

What are the lobe lifts on the two camshafts?

Looks like .280 and .282 with a caliper

Cliff. Is that for both the intake and exhaust lobes? The standard run of the mill EDB camshafts for the 1957 cars was 0.266” for the intake and 0.284” for the exhaust as checked on some used 1957 camshafts I have reverse engineered.

Exhaust, in the center of the lobe, will make a better check when I get time.

I wonder, has anyone ever sat down with Ed Iskendarian & asked him about it?.. I know he worked on cams for y-blocks some & possibly for the factory?. I know that the Oval short Track engine builders liked Isky's E-2 grind alot..

I was going through some old material, and found a copy of a page from some unknown magazine. It indicated that the 285 engine had an Isky E-2. I also found a letter written by the late Richard Gaston. He claimed to have worked at Holman-Moody in the day. He said the 285 came with the E-2 cam from the factory, with Ford markings instead of Isky markings. Then in his next sentence he said that the 290 degree cam had a noticeable lope. The E-2 was a 256 degree cam in those days, with timing events very close to the factory standard 256 degree cam. Rich was retired when he wrote the letter, maybe his memory was a little like mine is, a little fuzzy at times. I wish he were still around, I would try to get more info about the 285.
