Howdy all,
Well I decided to not try to use the Holley that came from my OMC 460 and just buy a new Holley carburetor for my 292.
So I called Holley tech support and they recommended this one: http://www.holley.com/0-8007.asp
They also have a throttle position sensor kit that works with this one so it should be perfect for my 292/E4OD combination....
It's a 390 CFM 4 bbl. Anyone have thoughts/opinions on this? Specifically, should I be concerned that it's only rated at 390 CFM?
Thanks,
Rick

There are three Holley type carbs I would consider for your application: (1) The Holley 390 CFM you've already mentioned (2) The Holley "Truck Avenger" 470 CFM (Holley 0-90470) (3) Barry Grant Road Demon Jr. 525 CFM The Demon is a Holley derivative design - uses all of the Holley small parts. Don't overlook getting one of these carbs as a "factory rebuild" version - they are often quite a bit cheaper than the brand new ones. These are carbs that someone has returned - usually (according to the factory) because the new owner couldn't get them on and running properly. They usually strip the carbs, fit all new gaskets and small stuff and then run them through a 'wet" calibration test. For all practical purposes, they are new - just a $100 (or more) less. I bought my little 525 Demon for $180 and it looks and runs just like my neighbor's "New" one.

Hi Steve,
I did look at the "Truck Avenger" too.
I did try a couple of CFM "calculators" and it appears that the 390 CFM would be more than adequate for a 292..... after all, it's for a truck, not a hot rod!!
The "Holley Guy" I talked to also suggested looking at the "returned" carbs too for the same reason. I think that would be an excellent choice. I did check ebay where they actually sell a lot of them and didn't see one as of yet. He told me that they're putting them there all the time, so I should check frequently.
I just wanted to ensure that I don't select under-sized carb....It appears that either the 390 or 470 will be a good choice.

A few thoughts from my experiments with carbs over the last few years, FWIW (on a 56 sunliner with 292/F/M) The holley 390 is easy to tune, but hruns out of breath at higher RPMs. Mathematically it probably shouldnt, but in back to back runs vs an edelbrock 500 cfm, ithad noticeably less top end power. However, id had better throttle response and started easier. Edelbrock 500 carb - pretty easy to tune once you figure it out, good top end power, not very crisp throttle response, and a really slight stumble if you try to cruise slowly right after idle/tip in. Its been that way on every carter/edelbrock ive ever worked on or ridden in....not noticeable unless you do a lot of slow speed cruising (i.e. parades, etc, and even then its not bad/embarassing/bothersome..its just there) Demon - I tried the route of getting a reman demon from Jegs. It was a mess. Missing retainer clip on the secondary rod, beat up float bowls, god knows what else. To their credit, Jegs immediately offered to sell me a new one at the same price, and I returned the reman. However, the new one has been crap too. Ive not been able to get it to run right, and every time I take it apart to change jets, PV, etc, I find more and more metal filings/shavings and gasked chaff floating around in there. As soon as I get the car running again, IM going to give it one more try and if i cant get it to work, im going to call jegs again to see if they will swap it or what... really disappointing, as most people rave about demons. Just a few thoughts, FWIW

I've heard a couple of stories about gunky Demons - but I haven't seen one. My neighbor's new one hasn't hiccuped, and mine (the rebuilt) had to have steel needle and seats installed to handle crummy gas. After that, no worries. If you want to try one or price one call R&D Racing 952-469-3219. I know more about de-bugging and tuning the Holley style carbs - so that's the way I went (45 years of tinkering). Seems to me the vacuum secondary has to be a basic advantage over the Edelbrock / Carter style outfits. I haven't seen any comments about the "Thunder" series with the Quadrajet style "air doors".

Based on what I've learned, another one you may want to check out is the Holley 465 cfm model L 1848. It's intended for Ford transmission setups, although I don't know about the AOD. In the recent carb tests written up in YBM, it was at the top of the unmodified units. Also, a buddy put one on his 56 with Fordomatic & was very pleased with it. Another possible one which is seldom discussed is the Ford Autolite 1.08 "flat top". According to Pony Carburetors it's one of the most trouble free & economical to operate 4 Bbls ever built. They were used on early Mustangs etc. It also tested well in our moderator Ted's, carb testing. Unfortunately, you can't buy a new one, so it's used or a rebuilt.

I have a 600 CFM Holley on my stock 292. Does great.

I have a 465 0n my 55, more than enough carb, a very good choice. Gary

Birdman, did you have to adjust the 600 cfm much to get it to run well? I've got an Edelbrock auto carb on my 312 marine engine and want to replace it with a marine carb. I'm leaning toward a Holley, but would rather go with a 600 CFM 4160 rather than the 450 CFM because they cost $100 less.

Rick, when you called Holley, did they say that the 390 carb would bolt right up to your 292 or do you have to change the manifold? I want to keep my teapot but for reliability and tuning issues, the holley sounds pretty good to me. I have a 292 with a merc-o-matic, I hope you keep us all posted as to which carb you end up using and how it turns out.

Kevin: According to my Buddy with the 56 car, the 465 cfm is virtually a bolt on. (with a B intake) According to Ted Eaton, it's intended as a modern replacement for original 1957 Carbs.

Paul,
Would "bolt-on" include the stock Ford linkage setup? Also wonder about OEM air cleaner fit?

They didn't say. But the 4160 I pulled from my old OMC (Ford) 460 bolts right up and those carbs are "square-Bore" 4160's too.
I am also going to use it with an automatic trans, so I made sure that Holley's TPS kit is also available so I can tell the Baumann TCS where the throttle is when I mash down on it!!!

This manifold in the attached picture is an ECZ-9425-B and it has the Holley 4160 pattern mounting flange. Seems like every time we show one on here the price goes up $25 on Ebay - so brace yourself. The tricky part is the four holes in the deck - they don't match a Holley 4160 600 CFM carb for bore size - but they do match the 390 CFM and 465 CFM carbs mentioned above. 
They are commonly and successfully modified to fit the larger carb bores - but if you just bolt a 600 CFM version on there with a stack of gaskets - there will be some issues. The manifold for the teapot is 9425-A and it has a decidedly different appearance. Adapters arre available for the "A" that allow mounting the later pattern carbs.

Yes,
That's the manifold I have for my 292! I didn't compare the bore size but I'm sure that if I used a suitable spacer, I could do some grinding and probably match them up adequately.....Holley tech support did suggest I NOT use the marine carb so I decided to go with the 390 or 465.
No matter though, I put my 4160 (650cfm) marine carb on ebay a few days ago and I can't believe it......They've bid it up over $150 so far!!!
I didn't think it was worth much until I started pricing new carbs!!

I run one of those 465's and the stock linkage fits the throttle lever just fine. I cannot comment on the early teapot air cleaners working, but any 4 bolt 2 barrel or 57 and up air clean will fit.
I had to increase my squirter size along with a pump cam and it has excellent throttle response and even accepts the factory choke setup on the cars.

I think as long as the Holley throttle position sensor kit works with the 465, it'll work great!

??????????? Um, one needs a TPS so the transmission controller knows where the throttle is!! I got me one of them hi-tech transmizzions!!
