Default Looking for the right carb

Having the blown motor in my 79 Scout II replaced with another 304 and am looking for a good carburetor. Been reading a lot of mixed reviews so I thought I would reach out to some of you guru's. First project Scout and would like to start off on the right foot, from what I'm reading rebuilt carbs can be your best friend or worst nightmare so I don't mind spending the cash on a good carb within reason off the bat. Would like to eventually make this an everyday driver but I bought this thing for a reason and hunting season isn't that far away.

The best carb is usually the oem one that came with it. What carbs do you have and what's wrong with them?

With the 304, you've got a 2bbl intake. I'm not a fan of adapters to stick a 4bbl on a 2bbl intake. There's nothing to be be gained by it and it looks silly. So, if your Scout is no longer subject to smog inspections where you live, the best out of the box brandy-new carb option is the Holley model 2300 list 0-7448 rated at 350 cfm. Don't confuse that one with the list 4412 version rated at 500 cfm. That one is way too much carb for any IH engine. They're very similar in appearance.

And to add to the discussion we sell the Holley 0-7448 by itself with a manual choke or you can buy it from us jetted for your application with an electric choke installed.

Jeff:

i know enough to be dangerous

I am considering buying the 0-7448 from you guys but I have a couple of questions. Read an old thread by M.Mayben and he said "Ya MUST use either a Holley-supply or a Felpro-supply "insulator" along with the proper base gasket on each side of the insulator. Also, the air cleaner neck required will be 5-1/8" opening, VERY common aftermarket size. The OEM air cleaner if your carb was a Holley 2210 WILL NOT work without changing out the base plate."

Do you sell or does the carb come with these parts Mayben is referring to? Can I use my current air cleaner?
Please advise.

I have an 800, 1970 304. Currently having issues with rebuilt 2300, man choke and no connection for distributor advance vacuum line. The spot where the gas line hooks up seems different on the 0-7448 then my current 2300. See pic. Will I need to replumb metal gas line?

I also read a post about adjusting the throttle cable so the flap opens all the way. Please advise.

@428street; Your air cleaner, if it fits the current carb, will be fine for a new 0-7448. And it looks like you have the insulator plate under your carb, too. Just make sure you put a gasket on each side of it, i.e. manifold, gasket, insulator, gasket, carb.

You would want to make sure it goes to full throttle when you mat the loud pedal and yes, you will need to do some plumbing of the fuel line for the new carb.

You can't go wrong buying a carb already set up from IHPA. Jeff will take care of your needs.

And please don't try to use a 0-4412 500 cfm, no matter how enticing it seems. That carb is for circle track racing on 350 cid SBC mills that turn upwards of 8,000 rpm. It's not meant to idle that good, usually way too fat or function cleanly just off idle. They can't be tuned, no matter what others claim.

Thanks Ray...I'm going to call on Monday and talk to someone before I order. I did not know that I needed two gaskets. When I got this carb back from the rebuilder it came with this what I thought was the gasket but I guess it's an insulator.

That big flat metal plate under the carb is the insulator. For it to seal correctly, it needs a gasket on each side. I'm sure IHPA will set you up on that point. That plate helps prevent fuel boiling/heating from the manifold. Be careful about tightening the carb down, though. The insulator might have the plastic bushings in the holes and you can crack them or warp the carb if you go medieval on the wrench torque. Follow what IHPA says about mounting and connecting it up.

I had an obviously PO Virus-afflicted Holley 2210 on my '73 1010 pickall with a 345 in it. At MM's advice, I put a 0-4778 on and never regretted it for a moment. It was a bit fussy about that electric choke setup, I think I ended up setting the choke spring 2 notches rich. All of my driveability issues disappeared and the mileage jumped up, too. It's worth the effort, for sure.
