Exclamation Re: Holley 41XX Modular Series Carb Stuff

Mike,
I assume you are the carb person that was recommended to me by IH north, I have a 73 Scout II with 392 and a Holley truck avenger 470 I think. I have had this Scout for almost ten years and close to fourty thousand into it and it has never ran good. Everyone I talk to tells me how well they run and how strong the motors are but I no nothing about that. I live in your area and would really like to speak to you outside of this thread. I hope you can help me get my beast running good.

Welcome wayne. Always good to have another orygun boy copping a squat around here. Mike is the man. 40k is a lot of cabbage to put into any vehicle and still not be satisfied. I too have a '73 392 in my Scout and am quite pleased with the power output. It has the original 4150 which Mike was instrumental in helping me rebuild from distance. I provided the braun, he provided the brains. If you've got plenty of patience and the willingness to learn, the carb king will get you squared away in due time.

Sorry I missed this post wayne! I'm on the road right now and will be home tonite. I hope to be back in the normal comm loop Saturday mornin'!

Anyway...welcome to the krew here...and we're neighbors (well close, just across the ridgetop!). We do fairly reglar "work days" at my place in leaburg so feel free to join in! In fact...depending upon how long since the carb was surgically opened up last, maybe the best deal is a work day/training session? No charge for that other than ya pay for parts/materials used! Ya might even git some flapjacks or smoked chupacabra outta the deal too? And I do have an oldskool exhaust gas analyzer that can prove out the carb...with two folks to use it, we can look at the carb running down the road (it's portable).

I'll be dam glad to help ya out with yore carb stuff. I got no setup info onna 470 ta for a 392 but it ain't hard ta work out, we just need ta start from scratch, no big deal. I've often wondered how that mixer would work out...I have set one up onna 345 though and it was superb!

And this dam orygone alkeegazz we're forced to buy now is killin' carbs left and right! So we can take care of everything at one time!

Why don't ya start a new thread here just for yore 470 ta onna 392??? That will keep all info regarding that in one place and will help in future searches for folks? Start that off with a detailed breakout of your particular app, engine mods, ignition system, useage patterns, etc. The more deetale the better! Then we can discuss a plan on the phone and get started.

Well mayben, I put hooty thru his paces on several steep and slimy hill climbs this past Sunday, and I'm pleased to report that he conquered every one and didn't cough, sneeze or fall on his face onct. Somehow, despite all the bullshittin' and beer swillin' you managed tuh git sumthin' squared away on him in monte's driveway! You did have the auto choke set a little lean though. It wuz pullin' open a smidge too early, so I went two steps richer and thangs seem happy. The fast idle does not step down automatically even as the choke plate approaches wide open. This must be due to the piston sticking inside the housing? One quick pop of the loud pedal cancels it back to normal idle, so it ain't no biggy. Thanks again dude! Hope kathy's feelin' good and ornery again!

Michael, share some of your wisdom with us about the effect of the emulsion holes into the main well from the high-speed bleed. In the stock Holley 4150 there are two of them with about a (going off memory here) .072 primary hole with about an .028 to .031 finishing hole into the high-speed bleed well. I see the trend in current high-performance cards to add 3 more holes (5 in total) and they are threaded so that you can 'adjust' them. The air bleeds themselves on top of the carb are threaded so that they are adjustable as well.
What situation would prompt one to play with these 'e' bleeds, and what would you expect to accomplish. Thanks buddy, I just know you can clear this right up for us poor, old hackers out there. Oj

Don't know where to post this but it might help someone here.

Did an install of: Holley 4160 (new style), jegs .75" spread to squarebore adapter, jegs lokar style throttle/kickdown bracket, and lokar cables.

Had to remove some metal off the bypass housing as seen in the 1st pic. The housing also had a mechanical water temp sender on the side of it that had to be removed, plugged, and ground flat. I'm not sure if the sender was in a factory spot as the truck contains a generous amount of "southern ingenuity" that I'm having to work through.

If my engine was cleaner and the bypass housing paint was red like it was supposed to be it would make for a very clean ans simple install. 2nd pic would be better but my hood lamp was a bit bright.

Michael, I have a post pending moderation in the IH product section under "304 intake" by buckey And instead of allowing that through I would like to get going here. The post that is in suspension for moderation is almost identical to one I posted about 2+ years ago.... A little embarrassing, thought I had posted it on another site and now I know why I couldn't find it over there! It was my first post here when I signed up. You can go ahead and blow out that pending post as I think it belongs in this forum anyway?

I am about to undertake the installation of a 8007 390 cfm 4160 on my Scout. I purchased a nib secondhand rpt 266/304 manifold and I am putting it on a 266 in an 800. I am going to need lpg gaskets as the ones that came with the unit were damaged by the po when boxing it. I also need a egr blockoff plate and gasket. I am installing a known-good prestolite electronic distributor from a 1978 or 79 sii w/345.

Eventually, down the road I will do some motor work including lightening/balancing, linebore, boring 040, cam, rocker assembly refurb and maybe 1 or 2 other things we'll see. For now the engine has only 59k original miles but shows some signs of cam bearing erosion. Don't know for sure but also don't want to blow er up.

When I have the small stuff in hand I'll post up, take pics and document my progress or lack thereof.

In the mean time, do you have any suggestions for this setup? Do not assume anything, fire away, you have forgotten 100x what I know.

Everything that I know about the rpt intake manifold install is in this thread:

http://www.forums.IHPartsAmerica.com...fol-guapo.html

I'd certainly pull off both rocker assemblies and freshen 'em up, my suggestion is that your oiling issues for the top end is inside the rocker shafts in the form of heavy sludging.

Ihon has the lpg intake gaskets on the shelf for the 345/392, but I'm not certain regarding the 266/304. When you order the egr plate ask Jeff about those too.

I'd certainly always install studs for the carb mount, I hate it when bolts are used for anything like that.

I'm not certain regarding the air cleaner install for a s800 without a body lift...I don't think you will be able to also use the 1/2" carb spacer but that will take some thought. It's certainly not an issue otherwise as the spacer simply adds some height to the installation.

That's about all I can think of right now, I'm sure more info will come up. Post a new thread for your installation and I'll follow along!

Default Re: Holley 41XX Modular Series Carb Stuff

I was trying to find a oem Holley carb for a 392 with no joy, so I spent some time on the phone today with a Holley suppor tec. Holley still has the specs for a list 4313 carb from a '71 392. Using that info I worked with the tec to see how close the current model 0-8007 390 cmf carb is. What was found is that out of the box it seems pretty close.

4313 / 0-8007
front jets 51 / 51
rear jets 53 / 56 uses a metering plate not jets this is smallest
power valve 3.5 / 6.5

so a 0-8007 was ordered today. We'll give it a try on the warmed over 345 and see how it goes. With the comp 252 cam and headers it May be just right.

Darn I just realized I didn't ask about the secondary diaphram spring.
