My 66 has the stock intake with a 2 barrel on it. I'm going to be putting in Harolds 254/262 cam with 401/432 lift. I was looking for an intake with the oil fill tube and I picked up the c3bx for cheap and I also have a 600 holley vs. Do you think this intake will work alright and I know the holley is a little big but I was thinking it would be alright with the stiffest spring for the secondaries. Just looking to get a little better mileage with some performance. Any opinions on this combo would be appreciated. Thanks, Kevin

Kevin,

The C3BX is an old school manifold that was derived from a cross between the older C4B and C3B intakes.
It's mixture distribution is not a good as the current Performers but was very popular back in the day prior to the Performers being introduced. It will work fine.

I'm not familiar with your combo but the cam you are running is small and if you have a PG/3.08 or somrthing simular in a 283/327 a 600 is more than enough.... I have spun my last 327 to 6000 with a 390 CFM Holley 4 bbl and way back when took my 1st 327 to over 6500 RPM with a 500 CFM AFB..... A 600
will work fine but that much air is not likely needed... Do you know the list number on that Holley.... They made a bunch of different 600 CFM holleys with vastly differnt idle and power circuits.... Some specifically designed for power , others as universial carbs and others as emmission carbs.... they may flow the same amount of air but are different carbs.

The number I got was 1850-4 and under it was 3224. Harold recommended that cam and I have the pg/3.08 gears with exhaust manifolds and duals. I was looking for an intake with the oilfill tube because I like the oldschool look and found this one for cheap and its in nice shape. I couldnt find much info on it since it's probly older then me. Thanks for the reply. Kevin

The 0-1850 series of carbs actually traces it's roots back to the old obsolete Y Block (272-292-312) type Forf engines of the late 1950's. It was in fact an OE carb
back then.At that time Holley was an OE producer and not really an aftermarket company.

Anyhoo it just so happened that the 0-1850 600 CFM carb was just about perfect on many of the engines of it's day... 352 FE , 348/409 Chevy , 361/383 Mopars , 389 Pontiacs and 370/394 Olds ect ect...Holley modified it was a different linkage and
and changed the circuits around alittle bit and offered it as a " Universal " carb with a manual choke.

These have idle , main and power circuits rich enough to work on most engines in the 300 to 400 CID range.But they are not specifically calibrated
for any praticular engine combo.... So beings that they are a " Universal " carb it may or may not be correct for your application.

You will likely find that some amount of tuneing may be required to make it run it's best with your combo... It's not optimal but it will certinally get you down the road quite well.

Thanks for the useful information Al. Kevin

Sorry ,bout this everyone.

It's been brought to my attention that one of my references above was incorrect.

I mentioned the 0-1850 was available on the Y Block Fords.That is INCORRECT. It was used on the 1958-1961 Lincoln , Merc 430 type engines....

My appologies to all for any inconviences.

I wish to thank Dave for the correction. graemlins/beers.gif

No problem at all Al, but wrong again, the 430 Merc "W" type headed motor ran a great big long Autolite four barrel carb.

I got the one off my Buddy's '58, 430 Merc. and dumped it after I found out it wasn't a 780 Holley.. I didn't even know Autolite carb's were made at the time..

And the old "Y" blocks ran those funny looking four barrel carb's with the butterflys up where you could see them looking at it from the side/front???

Mighta been the external choke butterflys?? They were kinda a weird domed shape, if not mistaken??

PDQ,

In my Holley Illistrated Parts Catalog 36-51 Rev 2 (circa 1975) it shows the R1850 as OE on those old Ford W 430 engines....That does not however mean that all 430's came with R1850's but some certinally did... At least according to Holley's info.... And from the info Dave mentioned in his EMail to me last night.... I was wrong about the Y Blocks tho.

No problem and thanks for the info Al..

Bttt, the old 3310-1 on an old C3BX was one hot combination in it's day and I would hazard a guess will still run darn good today!!

He, He!! Especially if you can buy both for like a C-Note vs several of them for a new RPM and a new 3310-2 or -3..

I've got a yblock engine outof a 57 fairlane with an oem holley that looks just like an 1850, it says thunderbird on the valvecovers.

There were a couple other OE holleys that resemble the R1850's... The R 1848 (465 CFM) and the 0-1849 (550 CFM) carbs..... both of these also were later ofered as cataloged aftermarket carbs available through the Holley perf catalog..... I have an 0-1848 sitting on the shelf here at home.

Did you look at the list number on the carb ? It is entirely possible that with those carbs being available for so many decades that anything could have been swapped onto them.... Lord knows how many OE pieces people have removed from cars and swapped other parts ( both OE and aftermarket ) onto otherwise stock engine..... graemlins/beers.gif

Then again it's not like the factories never made any mistakes and put wrong or mismatched parts on by mistake.... I think thats happened a time or two throught the decades. tongue.gif
