Looks like you could've been spreading the holiday cheer already by that pic.... don't lie to us - we're on to you!! 
ReAlLy?
You might have had us convinced except for
What else will we find once we run all the reflections through Microsoft Paint.
don't lie to us - we're on to you!!
Lol
I see the preponderance of evidence is against me...
I confess the radio was on 4:20 AM also....
Hear is the preview of the
Low Sulpher, Subbituminous, US sourced, Almost Eco Friendly, Lump of Coal!
I shall be receiving from Saint Nick this year.
Merry Christmas StangNet!
Daughter home from college for summer (made deans list) .
Old job hired her back instantly so driving Cobra last couple weeks.
She’s young and doing nine day stint right now.
Needed new inspection sticker again.

I hear it surging a little as she comes and goes.
and see fuel leaking marks by carb base.
So checked for vacuum leaks by spray and visual.
Found one vacuum cap that was iffy.
Got a carb kit that was enthenol compatable.
Thought power valve was problem.
its bowl was wet. I think thats the leak.
Power valve and cover were only finger tight from gaskets shrinking I think.
It seemed to test ok with spring compressing at about 7 plus inches of vac.
It has a 7 and a 5 on it and didn’t seem to leak down any.
So put it back together with new filters and cleaned radiator doughnut magnet .
Endless ferrous shedding in this block.
Scaraficial anode has disappeared off shaft so time for a new one of those.
Good to go for a bit.
Wish someone would paint it.

I thought kids would argue over who got mini van with working AC
But it has not materialized that way. Son drove it last night in fact.
Kind of comes down to parking order.
Daughter says she likes the thumbs up she gets in it and people who want to talk mostly want to tell you there Mustang story.
We Love this car

I think you've got the wrong part on your engine..... that doesn't look like a proper intake manifold to me..... 2 round holes?
Seems like it should have bigger holes, maybe like this one?
I believe this one is @Noobz347 approved!

You know, I saw this the other day and thought "I have one of those in my shed doing nothing...." - so this morning I decided to look up estimated shipping costs to Hawaii for
s and 
s. UPS is insane, but USPS isn't really too bad considering.
While that manifold isn't really all that great for a high performance build, and I think you might lose some bottom end compared to the stock 2 barrel dual plane, it's yours for shipping if you're interested. I'll have to dig it out of my shed and figure out how to box it up, other than that I'm not really out anything. Hell, I even have all those Holley carb parts that I could probably come up with an [almost] complete carb, if not fully complete, if you wanted that too.
No real updates on the Cobra, but I did rummage through the extra Holley parts I have stashed. I have all of these main bodies and probably enough other parts to put at least 2 more together. I ordered a rebuild kit for a 4160 to put one together, I think I'm going to go with the 1850-3 body. So I'll probably mess with the 650 this weekend as well as the gaskets that need replaced, then rebuild the 600 vacuum secondary and mess with that later.
This post is more for my reference so I don't have to search for this stuff later. This is the Holley PDF document for their main body part numbers and corresponding parts for a complete, off the shelf carburetor.
As far as this document goes, the 1850-3 and the 1850-2 are both 600s. They both get number 66 primary jets and have side hung bowls and both have 134-9 metering plates.
The 3910 is a 780 double pumper with 71 and 76 jets with center hung bowls.
The 3310-2 is a 750 vacuum secondary with number 72 primary jets and center hung bowls. It has the 134-21 metering plate.
And the 4749-3 isn't listed but appears to be a 600 vacuum secondary destined for MOPAR engines from what I could find through Google. Apparently these are side hung bowls as well, but I have no idea about the rest of it.
Edit: Pics are for reference if I decide to swap the metering blocks to get rid of the plates and use actual jets on the secondary side.
I mean the chances of me doing anything with that stuff is probably somewhere between slim and none.
Thank you, that is a good offer, and I appreciate it. Been wanting one that is shorter or maybe even a stocker. Like this ‘68
I have a Eldelbrock RPM and this one, and as far as I can tell - I’ll have to cut a hole in the hood for ether.
I’m getting closer to cutting it all the time
Eldelbrock performer 289 and its so old school its got the rear water passage still.
The RPM one was too tall to fit under hood, don’t know if this one will.
Will have to dig thur the carb pile to see what we can make work.
Of course it runs great the way it is...
Of course it runs good the way it is.

If the RPM is the same height as my knock off air gap, it would be a tight squeeze. You could probably run a larger diameter air cleaner with a drop base, but a flat base will definitely require the hood to be clearanced. (Ask me how I know.
) Of course a stock 4 barrel intake shouldn't require that clearance. And I think, iirc, the Performer 289 is just about identical to a stocker dimensionally - it might be slightly taller? But definitely not RPM tall. Of course, the only way to truly know is to....
Good is the biggest enemy of better
Oh, and to add to this - good is never good enough.
