500 CFM Holley for 259

[Mike Van Veghten]

First question...what is it...a 450 or a 500cfm?

Simple answer....yes, either will work fine.
It'll be up to you to correctly jet the thing though.

One word of caution...if it's got a lot of use under it's butterflies....the throttle shafts may be loose and will drive you nuts because you can't tune it or it won't hold the tuneup you give it because of the little vacuum leaks at the shaft to the base plate bore!

Personally...I wouldn't buy a carburetor you don't know the history of!

Jeff - while in theory...the "posibility" of what you say may be "partually" correct...I'd enjoy the action of a cylinder with no comperssion rings (2) on it...and see just how much fuel enters that cylinder.
In actually...it's a combination of pressure AND suction that make an engine work.
One note of things to ponder...why do flow benches "pull" from the valve side (intake) rather than push from the manifold side? Would be just as easy to design the bench to work either way...but no one does!

My comment about Holley's is just my opinion.
I based it on a few years of experience with both Holley's, Carter AFB's, Weber AFB's, Edelbrock AFB's and some off the wall stuff.
Most Stude owners that just want to bolt a 4 barrel carb on their Studebaker and go.
I'll leave it it that...

My preference for a Holley 4 barrel is based on probably very similar experience. But it is also just an opinion. (We'll get into the spark plug debate next )

I really doubt, however, that you can bolt a 500 CFM Edelbrock out of the box on any Stude V8 and go. I have heard they will work fine on a 225 HP 289, but I doubt if they will work on a 221, 232, 259 305, or any R series or modified Stude V8 without some tweaking. I believe it is probably a good coincidence that they work well out of the box on a 225 HP 289...but may work even better even on that motor with some tweaking.

I have to say to the credit of both Edelbrock and Carter, that both carbs perform surprisingly well right out of the box. As long as you pick the right size for the application. I've used them on a few Studebakers, a few small and big block Chevy's and a big block Ford. They really are tuned well from the factory. Yes, it is important to dial them in -but you really can bolt them on and go in most cases. I have their strip kit and love being able to swap different needles in for different situations. In my first few years of college, I would drive back and forth between home and school (150miles). I used to drop in a set of needles before leaving for home so I could get better gas milage. Then when I got back to school, I'd drop in the pair for light to light driving. This was in my '62 GT Hawk. I also run an Edelbrock on my cigarette boat. I frequent a lot of lakes with various elevations. Having the ability to change needles on the fly in a few seconds makes the difference between getting on plane with a full tank of gas and boatload of people or having to re-prop my boat. Anyways, I'm just glad you can buy them new. FWIW the needles and jets are swappable between the Edelbrocks and the Carters. Just my .02 cents

the edelbrock isnt a bolt on and go and niether is the holley depending on your intake holley would need an adapter plate the edelbrock a 1 inch spacer. you also have to drill them out at the throttle shaft to bolt up the linkage. i have used both.

What specific Holly would you suggest for an R-1?

In case you didnt notice carters arent made anymore. edlebrock is a good copy, but i believe carter went under for a reason. holleys are better!!!!!!!
anyone that has had trouble with a holley had a crappy rebuild or someone that doesnt know how to tune. they are the simplest easiest to deal with carb out there. we put a 390 cfm holley on an 83 camaro recently tuned it in and had a 34 mpg car that ran high 14's. no thats no barner 1/4 mile time but hey drive it to the track and drive it home getting mileage most econo boxes dream of. i dont understand why everyone on this site is opposed of someone thinking out of the studebaker box? what mufflers do you run? why are they NOS? they must be the best studebaker engineers picked em out.

a 259 will benefit more from a small cfm carb and frankly a 500 CFM isnt small enough i ran one on my 259 i went back the 2bbl the edlebrock 500 works great on the 289. the 259 needs a little less and holley makes a good carb!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! as does edelbrock wake up!!!

Is the r-1 stock? is it a stick or an automatic? how is it geared? what do you plan on doing with it?

if it is stock and an automatic. i would stick to smaller than 600 cfm. holley makes a street advenger that is 570 cfm it is a great carb. another good car is a street demon 525 cfm it would work well to.

if it isnt stock it really depends on what has been done. cam, compression, headers, valves, port n polish, intake? but i wouldnt go huge probably stay in the 650 range at most might even stay with the 570 street advenger, the classic 600 or 650 and might even creep up to the 670 street advenger.

i have thought several times about ditching my wcfb carter for a holley, but i would like to stay right about 500 cfm and holley makes a 450 and then the 570. i think my 289 is stock non r series it would be overkill and the 450 is mechanical secondary which i dont like for the street. not to mention i think 1 of these days i will make it to PSMCD with it, but who knows. those are my opions if anyone else want to give one...

It's real tough to "bog" with a vacuum secondary Holley that is at least close to the correct CFM for the engine. The secondaries only open as the engine demands more air/fuel.


Holley has an interactive carb selector here...

Bone stock.....4 speed with 3.54 final drive.

i would go with the 570 street advenger...... the vacuum secondary is real easy to taylor to the way you want it to come in. you will probably like it right out of the box though

Any issues with the linkage, and air cleaner?

you will need a small spacer under the carb and have to drill out linkage hole to match the stude thats all i remember doing.
