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?

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

Any Holly paperwork in that garage find?

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.

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.

Neat setup.  It uses the early Holley model 2300 2V carbs before the fuel levels went to being externally adjustable.  That puts the carbs in the late Fifties era.  More detail would be needed at the base of the carbs but I suspect there’s some kind of adapters being used on a three bolt intake.

I’d be interested in testing the setup on the dyno mule just to compare the results against the other 3X2 setups that have been tested.  If the intake is not for sale, then could the setup be loaned out just long enough to do a dyno test?  As the setup has been sitting awhile, the carbs would likely have to be disassembled and freshened up but that can be done on my end prior to testing.  Knowing that the Stromberg carbs are undersized when used with the better 3X2 intakes, then the newer Holleys regardless of the adapters are expected to see a horsepower improvement.
