I didn't have any hood clearance problems, but I am only using a 2" tall open element filter. I noticed a considerable difference in going up hills. I suppose that some of my big improvement may have had to do with a bad 1 brl carb but I don't think that was the case. The carb I put on is a 500 cfm, I don't know if that is too big or not, it was what I had so I used it. A smaller 2brl might be better, might be worse, I have no clue as to which is the case. Good luck, let me know if you like the 2brl or not.

 

Hey my stupid Carter carb. just quite on me for like the 5th time. Where are you guys getting these 2 barrel adapters? Would I be able to get NAPA or O'reilys to get one for me? I can get a hold of a few stock carbs for free off a 302 or 351. Anybody know the cfms on these? I own a 86 F-150 4x4 300 4spd.

Clifford Performance has the adaptors, they have a website but I cannot remember the address. I don't know if the carb off of the other engines will work or not, if they are stock Ford 2 brl's then I THINK that they should mount up the same as a Holley 2 brl.

 

I plan to use a stock Ford/Holley 2bbl, got 3 of em! I ordered my adapter from Clifford Performance (56 bones), you can get their phone number from the website "clif***************.com" I would give it to you but I don't remember what it is. My stock 1bbl carb has and still does serve me very well, the engine runs so smooth and quiet it doesn't even shake the truck. I have good power on and off road whether I am in high or low range. Has very good acceleration. But when I put a good sized load on er, she bogs a little on the hills, I just want a little more power on tap just in case I need it. Unfortunately Uncle Sam has me in Okinawa Japan (USMC) for a few more months, so I will have to wait to try out the new mods.

 

Yeah I've been to Clifford's website before and all I hear from everyone else is bad reports about Clifford. I was just wandering if there was one to be found without having to send it through the mail and spend that much.

I don't think anyone else sells them except for Clifford because they make them. As far as I know no one else makes them besides Clifford and no one else sells them for Clifford. I didn't have any problems buying mine but I wouldn't buy anything else from them.

 

I have to agree on that one, while Cliffords parts may be really good, the prices are outrageous on some of that stuff! Cams and manifolds and a host of other parts are available through other companies too, you just have to know where to look. I highly doubt you will be able to buy one over the counter, unless you get lucky at a swap meet.

 

Yeah, I stopped at O'reillys yesterday and bought a rebuilt. It's working great but it cost me 163 bucks. It's remaned be holley though, so shouldn't be the worst thing. I really needed the truck, so I had to do this, otherwise I'd get a 4-barrel intake from Offenhouser and a Edelbrock carb.

P.S I got 5th place out of 25 tractors in a tractor pull a few days ago, with my farmall H.

 

Have you tried j c whitney?
I fought a lame 1 barrel for years. The one on my 72 was so wore out I had to replace it so I went to buy a new one and got talked into a Holley reman. It was basically a piece of junk and after several attempts to get the accelerator pump to work right, I finally re-engineered it and it has worked great since. I have rebuilt several of those over the years and setting the accalerator pump has always been a hassle. It has so much slop in the linkage you really don't know which side of the slop to measure from and the basic design doesn't even require the plunger to return fully or predictably. I cured this inherent design flaw by placing another spring between the accelerator plunger mechanism and the top of the carb on the inside when I put the carb together. It doesn't take much of a spring and I think I used a cut down fuel filter spring from a quadrajet. Now I get a full stroke on the pump and a good healthy squirt. It has improved the drivability and cold weather starting an amazing amount. Any one who has tried to rebuild one of those carbs will relate and that is the same carb they used up into the 80s so the trick should apply.
So, if you have tried to rebuild your stock 1 barrel and it runs a little flat you might want to try this trick before you give up. It does not apply to the older carter carbs like my 68 240 has.

 

I rebuilt my original 1bbl Carter and it ran beautifully for a couple years, but my fuel mileage started getting really bad. Once I calulated I was getting around 4 MPG, I was going through a tank of gas in only 2 days! Driving to school, out to lunch, to work, and then home. I eventually replaced that carb with a Holley Reman carb, and I have had almost 3 years of flawless service. Oh and now I am enjoying around 12-14 mpg in town and 16-18 mpg on the highway.

 

go to E-Bay and you can always find guys selling used Clifford parts and other Hi-Po 6 parts. I bought all my stuff there!

 

I just checked out Ebay and they have a 3 two barrel clifford intake and another seller has a clifford intake and headers that is going for $150

 

I Just bought a 2 barrel adapter from TD performance products for $15 it bolted right up with no modifications i noticed a little gain in horsepower

 

Unfortunately the stock intake and exhaust manifolds are so restrictive that they won't allow any real power gains from adding a bigger carb because the manifolds can only flow about what the stock 1 barrel has cfm sizewise. To get any real gains you have to upgrade the the manifolds to get the engine to breathe. The ideal cfm carb according to cubic inches X max RPM -25% is about a 350cfm carb. The stock ford two barrel from an older small block is about 500cfm. The benifit of using a 4 barrel is that you are not using the total cfm (unless you open the 4 barrels) during normal driving, and that allows you to get good throttle response and good mileage.

 

What do you guys think would be better? Headers or EFI manifolds?
