I once looked at a 57 "E" bird at a dealer who specialized in  55-6-7 birds in Cedar Rapids, Ia, Tony something. I remember him saying he thought it was an original because it had tubular push rods and dual valve springs. It had a stock idle, ran good, price was right but some how it just did not click with me. Annother person that maybe a good source of information would be Verne Schumann of Blue Grass Ia. He runs a parts business specializing in circle track engine parts, and still stocks Y parts. He advertises ocassionally in the Y block magazine. His business phone is 563-381-2416 I do not know how often is there. I think he ran F codes. I do know he "posted" G heads with bolts through the valve spring area. He also ran a NHRA record holding 61 Starliner. Very interesting and inventive guy.

Welcome to the group

You have jumped into a complex topic for your first endever.This is a topic that has eluded Y Block bench racers and experts alike for many years.

The only way to prove what was used is thru hard data documentation from Ford/Mercury or the players who were involved.

In your statements you address the M 260 camshaft setup as by being used by both Ford in there 1956 dual quad Nascar package and also the Mercury M260 race package.

The documented facts are that Mercury used the first Isky E2 grind camshaft for the M260 setup.

Ford had a different grind camshaft which was included in the Nascar package (Ford part# B6A-9000-B) for the Ford 260 horsepower setup.

The  M 260 Mercury (the Isky E2) camshaft was assigned a Mercury part number.

The Ford 260 camshaft was assigned a Ford part number.

The camshaft grind as well as the part numbers are different from each other.Merc and Ford were two distinctly different setups.All of this information is documented and verified.

The "street" 1957 dual quad "E" code 270 H.P. engine used the regular camshaft that came with the "D" code engines.This "D" code camshaft was also used in the "F" code blower engines rated 300 H.P.

No special pushrods,heavy valve springs or anything else were in the "E" 270 H.P. and "F" code 300 H.P. standard engines.Those heavy duty parts were used in the optional camshaft packages availiable OR as an upgrade suggested by Technical Service Bulletins.

The engine we are still researching is the "E" code 285 H.P. dual quad engines.

While the 285 H.P. engines are listed in the Ford parts books as engines that were built,there is little information about what they consist of.

Documentation has it that Ford was working on the 285 hi horsepower dual carburated setup and dropped development on it when the blower setup came to birth.

I personally believe that the 285 camshaft is the Phase 1 blower camshaft BUT there is no documentation to back my beliefs.

As for camshafts availiable in 1957-if you have some time research Dennis Ks postings about camshafts.As I recall there were around 10 different styles of cams speced (who knows if they were actually built??) from Ford for the 1957 model year.

There currently is no Ford documentation on file about the Isky RPM 300 ever being installed and called the 285 H.P. version.

A few of those RPM 300 camshafts have been found installed but has always been discovered on an engine that has been rebuilt.

Please as Dennis requested,if you have any documentation post it up.

We need new blood such as yourself to finish up this mystery.

Again welcome to the group!

P.S.-Note to Dennis K

I owe you an explanation on my Ford/Isky derivitive.

I"m still working on it and will get with you on it.

Jeff,

Would you please post, or at least reference, the specific documentation and resources that support your statements, particularly on the 1957 Ford 312 285 hp camshaft.

Thru the years there has been much "hearsay" on the 56-57 Ford/Mercury 312 high performance camshafts that has been recently disproved by factual documentation.     

Regards,

Dennis

Hi there I noticed the discussion on camshafts and it perked my interest....Actually Ford used a Mercury camshaft called the M-260 for the 56 dealer code dual quad and the "street" 57 dual quad. It came out sometime in 1956 on what I believe is called the Nascar or power pack setup...Ford used this cam as well on the 270hp dual quads in 57....The higher perfomance dual quad, the 285hp setup used what was called the RPM 300 camshaft.....It was an Isky grind....It was not a ford camshaft....This camshaft was claimed to develop 300hp...It required dual dampened valve springs and single piece retainers for the higher rpm...5/16 tubular push rods were also used, the distributor had static timing of 12 degrees vereses the typical 3 and 6 degrees depending wether you had  a stickshift or automatic...There was actually five differant camshafts available in 1957...You had the stock 256 degree, the mercury 260 degree, the isky rpm 300 cam, and two differant blower cams available....I have the grind #'s if interested...It's taken a while in talking to people and a bit of researching to find this information...

Tom, you are so right.  The seller is just 3 years younger than I, and I can attest to the fact that memories fade and change over the years.  His setup could be a good running setup, but it certainly isn't "correct" for a concours restoration.  The Edelbrock manifold is the first clue.

Guys:

Be careful if you are going to bid on this item.  There are discrepencies in the descriptions.  ECZ-M carbs are not dual carbs.  Also, the same numbers were given for the Carter carbs.  Merc 335 did not use teapots, but 4150s.  I don't want to kill his sale, and the current bid is not unreasonable, but as I said, be careful.

I was thinking you'd say CWC foundry.

ECK-C, ECK-D, EDB-B, EDB-D, and EDB-E camshaft lobe hardness b/p spec was 40 Scleroscope (Rc 30)min.

The lobes on later cams were induction hardened to Rc 60-50.

Hardness of the tappet crown were:

EAA-C cast iron Rc 50 min

EAA-D 5120 steel Rc 58 min

5752073 and C3AE-A cast iron Rc 55 min

From internet search-

CWC formally Campbell Wyant and Cannon Foundry Co. in Muskegon, MI is the largest supplier of cast iron camshaft blanks in the world.
