Ok - new to the forum (and y-blocks in general) but have always been a Ford guy.

Had the opportunity to help out a neighbor go through her garage full of stuff that her late husband 'collected' - he retired from Holley and passed away a few years ago. The garage looks like something from the show Hoarders but everything is loosely related to automotive.

Here is what I found - a Y-Block tripower manifold with 3 Holley 2v carbs and linkage. And while many of the parts in the garage had tags to indicate what they were, this one has nothing on it. Heck - it took me a while to figure out it was a Y-Block as I am not familiar with them and did not recognize the intake port configuration at all. I have done a little research but have not found enough examples to know if this was from the factory (although that would surprise me a lot) or if it was a dealer add on, or something done at home. I have not seen anything about this configuration being done with Holleys. Additionally, I can find no markings on the intake, at least not without pulling the carbs off. And while I am sure, someone is going to ask for #'s off the carbs - I do not have them at the moment - the paper I wrote them on is at home. Also - the linkage moves freely...

So what can you guys tell me about this? What do you think it is worth? And, anyone interested?

 

certainly not the usual 3 deuce setup in that they are much later carbs than the conventional 50=-57 2 barrel. as to value, depends on the make of manifold, and whats its worth to be person who likes it. definitely a neat piece.

Thanks! Here is one more pic of the manifold from underneath - not sure this will help to ID the manifold - I will probably have to remove the carbs in order to find some kind of marking on it.

Could be a regular old 3 duece manifold with adaptor plates to allow for the newer Holly carbs.

Carbs would have to be removed to find out what it really is.

Any Holly paperwork in that garage find?

Like Oldmics, I THINK some type of adapter has been used to adapt the four bolt Holley carbs to a manifold with three bolt carb. mounts.



Interesting the way the carb tops have been cut to allow the three to fit together. I wonder what was used for an air cleaner.



In your second picture, I'm intrigued by what appear to be vacuum chambers on the front and rear carburetors.



It doesn't look like adjusting the idle mixture screws is easily accomplished.



I'll be interested to learn what this set-up is made-up of! Holley numbers should be located on the front of each air horns near the level of the choke plate shafts. -The choke plate assemblies have been removed on the front and rear carbs, but the shaft holes are still there and open.



The manifold does NOT look like the Edelbrock 573 I'm comparing it to...

Thanks guys

I did not find any old Holley Documentation - but there are a LOT of 1V and 2V holley carburetors - including a handful of progressive 2Vs.

As for the additional details on this tripower set up, I will do some more digging on numbers and such and let you all know what I find out.

Very interesting setup. I agree that there must be adaptors for the carbs. I seem to remember an adaptor similar to this one for 2 barrel Holley 4 bolt to Holley 3 bolt.







This one is for Holley 4 bolt the Rochester 2 barrel.



The "lugs" for the four center manifold hold downs are squared off like a Edelbrock 553.







The idle mixture screws on Holley carbs are on the sides so mixture adjustment shouldn't be a problem there. It appears that the end carbs don't have the idle screws installed so you would only have to adjust the center.

Some OEM holleys of this type 320 cfm were fitted to international trucks and others and had mixture screws in front of main body. It looks very much like an edelbrock intake! The rear carb certainly overhangs the back of manifold.

Notice also the outer carbs don't have accelerator pumps and the chokes have been removed. Obviously modded for the 3 deuce setup. Also looks like the outer carbs are vacuum operated/modulated? So there would not need the idle circuits.



Remember the guy worked for Holley so he had excess to what he needed to make it right.



That's just my 1¢ worth...

Looks like it should be sitting on a  MoPar..
