The A manifold is hardly worth $75s. And using an adaptor often results in a misalignment issue at the plenum. The guys are giving U good advice to spend some extra for an ECZ-B intake.. The only minor note there is that depending where U live (North,South?) sometimes the choke heat tube in the  crossover of the intake may be corroded out. (mine was) So, if you will be running a std heat operated choke, U might need to replace it. I couldn't find one locally or readily, so I made one out of small copper tubing & a 90 degree fitting etc...

Spend the extra money and get the ECZ-9424-B manifold.   By the time you buy an adapter the price isn't that much more and you will have your choice of new carburetors.  There are plenty of them out there and the price should be half that of an aluminum intake.  A four barrel upgrade is worth the cost.  It makes a big difference in a YBlock.

Tell us what exhaust system you have-rams horns and duals, or the front cross over. Where you're going in the future. What goes in has to get out, and that all plays into the decision. I've seen some comments on more modern 2 barrel carbs that might work, or earlier 4 barrels that will fit the A manifold. All part of a system that works together.

Hi, my 2 cents....if you're going through the trouble of changing manifolds, get the '57 and up style to take
best advantage of the work involved. Where are you located?

The only drawback to the "A" manifold is  the Carb Bolt Pattern. If You want to  use a newer Carb like a Holley You will need an Adapter. If You ad an Adapter and Insulator You may not have enough Hood Clearance depending on what Vehicle You have. The ECZ-9424-B Manifold is 1957 and later and will accept most newer Carbs with no Adapter.

  

I have a '64 F-100 with the original 292 and I have been thinking of updating to a 4 barrel intake. The only modification to the (otherwise stock) engine is the addition of headers. Would upgrading to the EZC-9425-A intake be worth the bother? There is one selling for $75....is that a reasonable price? Any insight would be appreciated.
