Well everyone it's finally here, I am taking apart a Y-block that is Not Mine!!!!!!!! Can't tell you how good that feels. I am building it for a guy down the street for a 56 Ford. In return he is installing a "footprint gas pedal" on my truck (Joe Dirt). Just kidding he is actually doing some body work on my new pickup. When I disassembled it I found that one of the pistons was hitting the head and all the rod bearings were in really bad shape. The cylinder walls look fine but we will install new rods and pistons any way. I am not sure if the crank is fixable but we will see what the machine shop says. The engine was actually really clean and it must have came out of a mercury cause the valve covers said so. It had a cruisomatic behind it but we are going to install an AOD. He already got the cam from Mummert and if I remember it should have a pretty nasty idle and we should be able to make some power with it. I am excited to build one naturally aspirated and see what we can tune it to on the dyno. He already had the heads reworked a while ago and he bought a factory Ford aluminum dual quad intake and he found some exhaust manifolds, I am not sure what they are called but they come up towards the middle and go straight down. I will call John tomorrow and see what we can do for rods and pistons. I will probably zero deck the block to give us a little more compression. I was wondering also what you guys would recommend for carbs. The intake has a smaller bolt pattern than the normal 4150 square bore carb. I was thinking for an engine like this around two 400 cfm carbs might work well. Just have a couple pics of the engine I will take more as the project goes on.



The engine actually disassembled really well.



This is the piston that was getting into a fight with the head. The pistons are interesting how they have a little hole in the middle of them. My 292 didn't have that but I guess they were not Ford pistons either. It was neet even the valves have an Oval on them and say Fomoco on the them.

Another source for adapters to use later large base carburetors instead of Holley 4000s or Carter WCFBs

I've been told by several who know more about Carters than me, that Carter did not rate the WCFBs by cfm. That said, based upon throttle bore and venturi size, I've been told that the early WCFBs per the '56 Merc are believed to flow 375 cfm.

The original '56 Holley 4000s were rated by Holley at 350 cfm, as I remember. I have been unable to find that in writing tonight... I've got it in a listing in a late 60's Edelbrock catalog with a purple cover. Still digging...

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!
