John. As you’ve observed, the ECZ-C and FM255 dual quad intakes do work with the larger diameter distributors regardless of the rearward placement of the carb. The extended height of the cap on the MSD 8383 distributor does make it a bit touchy in regards to clearing the vacuum secondary diaphragms on both the Teapot and ’56 Carter WCFB carbs though. I had to install up to 1” of spacer under those particular carbs to clear the spark plug wires at the cap when using the Merc ECZ-C or Edelbrock FM255 intakes during the dual quad test. To date, the only documented instances I have for the ECZ-C dual quad intakes is it being used on the ’56 Mercs. It strikes me unusual that the ECZ-C casting number is actually used on the 1956 dual quad intakes while the ECZ-B casting number is introduced as the 1957 iron 4V intake. Just some ramblings here.

Thanks to Dennis, we now know that Schmeller Aluminum Foundry in Cleveland cast ~5500 ECG-D dual quad intakes for the 1957 Ford model run. This number appears to also include over the counter sales. Many of the ECG 2X4 intakes are identified either with a plain S or a S cast within a diamond on their bottoms which is indicative of castings produced by Schmeller.

Ted/ John, That's what I thought, which is why I asked.

John that format for machining location started in the Detroit area, I think. Edelbrock came to it later. We were using it at Winters by 1957/1958. I found early Scrub patterns with those locators and rests on some of the first ones we made. 57 FI intakes and SD Pontiac's.
Schmeller did FoMoCo, we did GM. Tells you something about my choice of Employers Eh?

Frank, some people get wiser with age.The ECZ dual quad, being a Mercury part was likely spearheaded by Bill Stroppe who was located in the Los Angeles area. I think Stroppe often worked with Edelbrock on specialty parts for Mercury.Thanks to Dennis for the production number on the ECG 2-4. No wonder they are the easiest to find.
I wonder who was the source for the MEL 3-2 intake.

I have spoken with John Harding, whom has a lot of factory documentation on the 1956 Ford and Mercury (M260) dual 4 barrel kits that were available over the counter at Ford and Mercury dealers. He also has a recording of an interview he did with Ed Iskenderian about these kits. I'm pretty sure I remember Isky saying that Edelbrock supplied the 2x4 intakes for the early kits, and a later more "Ford" intake was used after that.

The intake pictured here is what I believe to be from the early M260 kit and very valuable. These kits also came with two Holley teapots (LIST 1268), milled ECZ-C '56 heads, Isky supplied cam in some kits, lifters, springs and distributor mods. Plus all lines and fittings and special air cleaner. I may not be 100 % accurate here, but I know it has to be close. I also have copies of some factory documents that support a lot of this. It was all aimed at NASCAR right before they banned multiple carbs and fuel injection.

John, Maybe Dennis can find out. This all kind of points to the fact that if we don't document this history now, it will never happen. Is there are any former Mercury or Stroppe people reading this, please feel free to comment.

Follow-up to my previous posting on carburetor cfm rating. The 1968 Edelbrock catalog listed Holley carburetor applications for the O.E.M. car manufacturers, carb I.D. numbers, cfm airflow, venturi diameters, and throttle bore diameters.

The listing indicates that the Holley replacement carb for the 1957 'E' code dual quad manifolds was Holley part number R-1434 AAS, rated at 330 cfm, with 1 1/16 in. primary venturi, 1 in. secondary venturi, and 1 5/16 in. throttle bores both primary and secondary.

It took awhile to find the catalog!

The 1434 and 1437 dual 4 bbl. Holley teapot carbs also had rings that were pressed onto the primary boosters that reduced the CFM slightly on the primary side. So a single 4 bbl. teapot (LIST 1161) has the same size venturi's and throttle bores, minus the reducer rings. So think they were closer to 370 CFM.

Pretty sure they used the reducers to improve acceleration, since both carbs opened up at the same time. Not progressive linkage.

Gentlemen

Late to the party here.

As Sal mentioned Ed iskenderian said in an interview that I had done with him that Edlebrock did the dual quad castings for the ECZ intake.

I dont believe Stroppe was involved in this ECZ manifold design as Ed always mentiond the "back east" references to the engineering about the M 260. Perhaps Holman and Moody ?

As for the Merc 3X2 intake - that was a Stroppe design which was cast by Dean Moon.

As in Moon tanks and Moon eyes.

Those original intakes are identifiable by the small "Moon eyes" cast into the side of the manifolds.

Stroppe also did the 57 Mercury M 335 engines.I am under the impression that Buddy Barr did the castings on those M 335 manifolds but have no proof!

Great old stuff!

Well we finally got the parts back from the machine shop and I got the short block together. It is nice to assemble a Y again. I love seeing the the piston right at the top of the block and all nice and shiny and new. Here are a few pics of it so far.





Love how the pistons come right to the top. Sweet pop ups!!!



We couldn't help that notice that this brand new 2.8l Kenne Bell looks like it was made for a Y-block. We are contiplating doing this with our next Y-block. Sexy isn't it?



Ya it looks good.

Looking good guys. What kind of final compression ratio are you aiming for?
