It is the primary ports for the smaller throttle valves of the staggered bore carburetor like a Delco Quadrajet or Holley spread bore.

As best as I can tell from the Edlebrock website and the information you included, you have the wrong intake. The intake you purchased is for "C" or Cleavland engine or even a "M"; when what you have appears to be a "W" Windsor engine.

I put an Edelbrock carb. on my 86 chevy. Using stock intake manifold. I bought and adapterplate and now it is leaking fuel between the adaper plate and manifold. Can I double guasket it or should I tr


Did you use a gasket on either side of the adaptor plate an tighten the screws into the carby/manifold tightly. Check the float level in the carby to ensure that it is not leaking fuel out into the manifold as well

1973 mach 1 351c has an intake opening at head of 2.6x1.8. edelbrock manifold 2665 fits but the opening at intake port is 2.1x1.3 what is the purpose of smaller intake opening


I am going to take a few guesses here. Some intakes fit a wider range of products. Narrow opening could raise CFM draw due to funnel effect. Also don't remember if this year had 351/400 block. Some castings were taller, internals changed to drop from 400 to 351. Would not need big airflow for smaller 351.

You could check out the Elderbrock site for help. Difference between "Yea they fit" and "Yea, thats the right part".

Only 4 cylinders working


Hi,
Yep that could be it, once you have done this run a vacum gauge off the manifold to see what reading you get also.Check that the spark and fuel delivery systems are running correctly just too eliminate those 2 areas.

I am going from a qudrajet carb to an Edelbrock 600 with manual choke. I am not sure how the linkage switches over. I am working on a 1985 chevy 4x4 with a sb 350


If your staying with the stock intake manifold the edelbrock wont fit unless you install a adapter plate.And i would advise you not to install it will not seal properly.I would install a edelbrock intake manifold and carburetor as a matched set.You can purchase a edelbrock carburetor and intake manifold from advance auto parts that's designed for your vehicle.

I would look inside your distributor cap for cracks or debris. This is the genneral cause of a misfire. However, if the misfire is "rythmic" as in a timed pop pop pop, than you have a collapsed lifter or a bent pushrod. Thank you, Dana

To change to a 4 bbl u wil need to change the intake manifold, as for the heads only if u are going to preformance. Changing diffeent 2 bbls will not be of any advantage to you.

I need to replace the 2 barrel carburetor on my 1973 Mustang Mach 1. What size (cfm) and which brand would work best? Thanks!


If this is the stock 302 cu. inch V-8, the original carburetor will be a Motorcraft 550 CFM carb. If you would like an upgrade I wouldn't go up on the cfm's unless you do a intake manifold change to a competion intake such as a Edelbrock competition intake or other modifications (increased compression ratio, larger valves, higher lift cam etc.) that would allow increased flow.
