This is to pay for the high speed train that will route thru the Central Valley, that is...if it's ever finished. Pols have been talking about this boondoggle for years.

This is Moonbeam's 2nd time around, we got rid of him the first time with the battle cry: If it's Brown, flush it!
I am going to visit all the places that I want to see and I think that Aunt Blabby will want to see them too.
Excepting maybe the gun shops, I'm going to stop at a few to see if I can add a WinM1895 or two to my collection.
Question and it probably is extremely stupid to you guys but again I don't know crap about carbs.
Is it normal that the primaries are slightly bigger then the secondaries on a square bore or is that what makes it a spread bore. Looking at this thread these intakes look the same (I know the part numbers or casting I'd is different)

There are three basic types of cast iron 4V intake manifolds for the 351W. The 1969-70 car version, the 70s marine version, and the mid 80s HO truck (and van) version.
I have each in my parts storage, and after giving them a little examination I can report the following: They all appear to be the same basic low rise construction, probably cast from the same patterns. They share approx. 1.52" primary throttle bores and 1.625" secondaries. The ports are about 1.03" x 1.83".
The HO version has a couple of EGR ports that need to be plugged.
(Note: Shown Below)
The early intakes (up to 1974 or so) use four extra head attaching bolts and have different water passages as compared to later manifolds, but this can be worked around.
Here's the two early intakes for your viewing pleasure (I haven't yet beautified the HO intake so don't have a picture, but other than the EGR holes, it will look the same):
C9OE 9425-E
D5JE 9425-FA

E6TE 9425-GA or CA

Blabby suggested we rent a motorhome, but I said forget it, too expensive and the MPG will be terrible.
The only advantage, if we buy anything, it'll fit...if we can get it thru the side door that are usually no wider than found on a "Chic" Sales aka "Here's Johnny."
Motel rooms for the nights would be my suggestion (beds are more comfortable, more room, etc.) but the mobile bedroom makes sense to offer alternatives, we won't be restricted to stopping in any one place.
These things come in different sizes; we don't need a Winnebago, something half that size or smaller would be fine and they get better gas mileage. Something like a van conversion.
My opinion, for whatever it's worth.

Instead of playing CHINESE FIRE DRILL and spending a lot of money, take the 1405 and set it on that spacer. All throttle plates should clear. Being a square bore (1405) the secondaries bore size in this instance will not matter too much on the HOLLEY 4180C spacer as it is not a HP engine. Either keep or defeat the EGR System.
Try it on the bench. Raising the carb with a spacer/adapter might create even more linkage geometry problems than the ones you are going to encounter.

A standard square bore Holley or Carter (edlebrock) Carb will go on with no issues plus Edelbrock makes a square EGR Spacer plates that will cover the EGR port in the intake.
Not sure what all the confusion is about, this is not rocket science

And BTW it is pretty much rocket science to me cause I deal with fuel injection and the only reason I didn't make this truck efi is I want to learn how to mess with carbs.

If you want learn about cabs and how they function the easiest one to start with is an Autolite/Ford 2100/2150 they are dead nuts simple should be an easy find at the wreckers off any 60's thru early 80's ford with a V8 or V6.
Get a junker carb and tear it down every one here will willingly help ya along. when you have questions.
Not all of us are familiar with Holley's or the Carter (Edelbrock) but almost all us us are familiar with the 2100/2150.
Also do not overlook the Summit carb https://www.summitracing.com/int/par...00vs/overview/
It is a rebrand of the the Holley 4010 and the Holley 4010 is a modified version of the Autolite (Ford) 4100 4BBL most of the same guys that designed the 4100 designed the 4010
Many think the 4100 Autolite was the best factory 4BBL ever offered and some feel it was best 4BBL period.
The EGR spacer plate will cover the EGR port aftermarket spacer plates will not.

The intake exhaust cross-over can be blocked making the EGR port ineffective. But it requires pulling the intake.
Plain and simple, the only correct way to go about it is non-EGR manifold replacement, using the 4180C on the EGR Spacer or having a spacer /plate made to cover the EGR supply hole..
But the 1405 will go to the EGR spacer with only minor secondary misalignment that should not cause any problem. If not wanting to make SUMMIT richer, this is the way I would go (actually I would go HOLLEY).
No, it is not rocket science, but a problem (FORD) since 1973 that has not been addressed as it is illegal to modify emissions equipment.
BTW- The SUMIT CARB is a knock-off of the 4010 and made off-shore. If you want a true 4010, HOLLEY offers them reman. And yes it is a nice carb but they never caught on as they were not OEM to any manufacturer, sales were bad and so HOLLEY dropped production.

This also solves the spreabore issue short of finding a factory one off a 460 with the 4300.

You can also just bolt a plate in place of the EGR or leave the EGR in place but disconnected. There is no "correct way" unless you want the EGR spacer plate removed all together.
And it is illegal to modify emissions equipment in some locations but not all, even to this day it can be done in some areas with NO repercussions what so ever (short of voiding new car warranty ).
The summit carb is not really a knock off it is rebrand as Summit bought the production rights from Holley for the 4010. Sort of like how Edelbrock got the Carter,
And the way I read it the OP does not yet have the Edelbrock as he stated he will be getting it, and the 4010 is a much simpler carb to learn on and less expensive than the Carter/Edlebrock so just giving him options.
Given the choice I'd take a 4100 then a standard Holley but the Holley is not really the best carb to cut your teeth on and the Carter even less so IMHO. So the Summit 4010 is a good compromise and it seems to be have been getting reviews as good as the Edlebrock and possibly even better...
Personally Carters just don't look right on Ford engines, Chrysler yes Ford no.
Edelbrock Ford EGR Adapter 4BBL

This also solves the spread-bore D I assume. issue short of finding a factory one off a 460 with the 4300.
This is actually a service replacement for the FORD square-bore spacer. It allows re-positioning/mounting adjustment of the valve itself. It will not accept the 4180C.

What you are implying is skirting the law hopefully with no repercussions. When you make this assertion, the reader has to understand what he might be undertaking.
-Federal Regulation of Aftermarket Parts-
-Summit Carb Review and Road Test - 2009-
