Holley 2300-C carb

[Crosley.In.AZ]

I've been looking up Holley carb numbers.  Trying to find the CFM rating of a Holley 2 barrel carb... I think it is a 350CFM carb,but that may be wrong.  It may be smaller

I have numbers :

A tag number  324889-c92;  this points to a carb for an International Travelall  small V-8 engine in the late 1960's to early 70's.

Also , I find a similar  listing for Ramblers of the  early 1960's

I also found a  Holley list number ;  2040 for similar carbs.

i have a holley illustrated parts and specs book..

they show the 2040a and 2040-1a as coming on 1960 rambler 250 and 327 motors..

no listing of CFM ratings... they did show a throttle plate 9r-122 as the throttle blade part number but i have not cross referenced it  to see what size ...  to compare it to other 2300 carbs... this is a model 2300C... and has the idle mixture screws on the back side of the base plate...

i have one of those in crappy condition...  probably missing some parts if you really need something...

i still have the R6425  holley that i showed before...   but that would be way too much carb of a six....


what other info do you need?    i can scan the section with part numbers verses ill numbers and the illustrated page.. 3-3 on holley parts books...

hi wayne,

I was curious if this carb was a 350 CFM rated.  I have two #4412 Holleys (500 CFM) that have larger throttle plates and venturies.   This carb I am curious about, the  venturies look too small for a 350 CFM flow rate , I could be wrong.

The list numbers on this carb have been XXXX out for some reason.  It also does not have the usual  Holley design throttle arm on it

I read through all the Holley pages of pdf files on carb list numbers.  Smallest 2 barrel 2300 series carb I found was a 350 CFM rated.  There are some larger rated 2300 series than the 500 CFM too.

nope,

:?

Throttle linkage is different on my carb.  Must be an OE application from a Travel-All or somethin

My carb actually has idle circuit adjustments in the throttle blade base plate.  The screws in the metering plate sides  are blocked off... this is an odd ball carb I found.

[wayne petty]

the carb number you posted... came back to an 64 to 70 international truck..

still no cfm rating...      

can you measure the throttle plate bore?

perhaps measure the venturi bore...

and.. yes...  international based carbs have a weird tiny throttle lever...

they use a 3/16 or 1/4" rod linkage ..

i like the idea of being able to fine tune

wait..  the idle mixture screws are on the back side of the base plate...

do the butterflys open backward?    tilt down from the rear??? instead of tilting down from the front/??

got pics???/   i might have to move a car ... open the vw van.. dig out the version i have...


are the idle transition ports on the front or rear... are the idle ports on the front or rear???

looking at the left side of the carb?   does the throttle lever open the throttle when moved clockwise?

why do i have the feeling that your carb was intended for something with a governor?

just a thought..


i got an 850 dp you could drown it with;)

I've said nothing about a governor ( although I am glad our previous AZ governor is gone)..... does the ol International  combines have governors on them?

I bought this carb ( hold on here)  sight unseen. When it arrived imagine my surprise to not find a 7448 list Holley carb in the box.  Seller claims a 350 cfm Holley carb  and it was cheap to buy

the venturies look slightly smaller to me than I would think they would be  for  a 350 cfm  carb....  a pure speculation by lookin at them.

I have a  original version #  3310 Holley 780 i can drown the motor with tomslik , thanks for the offer.

I am guessing that is set up for a big inline 6 in the original application. does it have a REO pump on it?

[wayne petty]

no, those carbs were for the various 266, 304, 345 international V8's

my holley parts manual does not list cfm sizes... nor does it list them by factory part number...

i can still do more research..  but most carbs are not listed by cfm...

there are also holley economaster carbs floating around... that have a weird booster venturi... excess amounts of webs across the booster venturi opening.  

there is one other option.. but they are almost impossible to find.. a holley 2305 ....  a what.. it is a progressive throttle 2 bbl 2300...   with the throttle linkage out the front and back of the carb...  i think they were also used on circle track racing...  

then there are the various motorcraft/autolite 2100 and 2150 carbs...   the 2150 carbs did not all have the high speed air bleed solenoid to allow feedback control... some used a power valve piston that was throttle shaft activated to lift the metering rods that hung in the air bleeds.. so the wider open the throttle .. the metering rods changed the air bleed sizing...   trying to stay in the proper fuel mixture through out the rpm range.. stop from melting the cats and get some kind of economy out of it...

as for governors on IH... yes some did have them...   those were 2300G and 4160G carbs...    usually the scouts and travelall's did not have governors.. the larger trucks did... to stop the drivers from overspeeding the motor...

one intresting thing... the ford diesel 6.9 and the earlier power strokes used what looked like IH345 internals..

for people who have a governor carb.. try if you have to rebuild it... to not take the governor apart to replace the  regular carb gaskets.... without a factory service manual... they are really really hard to put back to where they belong..    rpm wise that is...

I'll get a list  #7448   Holley carb next week and compare the venturi size on the two carbs...  I am curious about this


Wayne , most of the stuff I've read does not list a cfm rating either....  dont over work yourself on this... I am simply curious IF this carb is a 350 CFM carb.

[wayne petty]

can you look down the venturis and read the stamped in numbers on the throttle blades...

that was i can compare... to other carbs of known flows...

i googled it a different way... and found the application data over at the old car manual project..

The Vegas used a progressive 2 barrel holly.

[wayne petty]

the carbs on vegas were 5200 holley/ webers... yes progressive... but small...   one heck of a carb... very tunable... if you have the jets. idle air bleeds,  emuslion tubes, idle jets,  and the ability to withstand the time it takes to get them perfect...

gm replaced them with a variable venturi carb...  the varajet.. they were available in both normal operation... and feedback versions...
most people hate them....  they do not understand.. that there is an adjustable main jet under the screen... takes a special tool...   lock the throttle linkage at 2500rpms...   and adjust the main jet for best speed... or on feed backs .... till the dwell meter hooked to the green wire , set on six cylinder mode...  28 to 32 degrees of dwell.. again with the throttle locked at 2500 rpm

nope,  it has  the 30cc pump on it.
