intake manifold from the Russian v8
Hello, comrades.
In the photo the intake manifold from the Russian v8 zmz-523. The standard he wildly strangled and put in small buses, but it has potential.
As you can see, the collector for the two-chamber carburetor and bad design, and out I have two: convert to quad carburator or find a similar manifold of American motor.
Question: if you've seen on American engines manifold with a similar arrangement of inlet ports? The rest of the details do not matter - Improved file.

You have 2 very costly options, or you could just fabricate a spacer and use a Holley 500 carburetor. If that's fuel injected rather than nitrous-injected, then Holley makes a 670-CFM 2-barrel TB you may wish to adapt.
The more costly options are either sending that one to Extrude-Hone, or a fabricated sheetmetal manifold.
That one you have shouldn't be too bad if you add a Chinese turbo to pressurize it.
The length of the runners will affect the RPM range of your powerband even more than your cam specs, so if you want more RPM, then you'll need to go with a custom fabricated design with much shorter runners and a much larger plenum.

I think this motor is a copy of an old packard engine.
What a crazy design for an intake!
Looks like its heated by oil from underneath and ...What is that in the front?
Is it for an oil filter.
I would forget about the adapter deal,just fabricate one out of aluminum.
I would love to see pictures of the whole engine!

I try to do a minimum of money. This engine will be 100x80 5L (stock 4.2L 92x80). Carburetor - quadrajet or holley. RPM is planned around 5500-5700. The easiest option - to expand the site welding, but it is possible that the engine has been revised copy of some old American engine, and then have to be ready-made solutions. In those years a lot of things copied.
topwrench, Yes, in front of the oil filter. That's the whole engine.

/Out looking at packard engines/

By the way, to look like old-style collector. It should be better, but it is not possible to find. And almost impossible to convert to quad, as the site around the carburetor is the coolant.

Now through the gallery.
I do not see the edit button.
Moderators, insert please this photos in first post.

Go to youwill find the engine there

MTide 01-15-2012 07:04 AM

I'll try to look there. But an Internet search on packard nothing. Yes, the car, which first appeared on this engine - chaika, very much like a packard clipper 195x, but the engine did not like.
Everything that I have found the inlet box located either in pairs or windows 1 and 2 cylinders are almost the same line. And here the offset between 1 and 2, the cylinder is very large. 01-15-2012 09:25 AM

You won't find that in any Packard listing.. Yours is a modern design engine..

Thin wall casting. Insert, free standing, cylinder sleeves.

That's all 80's and later gasoline automotive stuff.. Commercial truck/tractor back to seventies..Pioneered the design in Heavy duty Diesel stuf

Maybe you didnt find it there. But I did!!!!
There is pictures of the zmz523 all over it,all I did is do a search n typed zmz523 engine,Packard did use it,also trucks used it,granted it wont be the same as the Russian copy,Packard designed the engine with American standard inch system n what he has got is , Im sure all metric.
By the way I coulnt find any 80as or later gasolene stuff in the Packard site.
The engine he has IS a gasolene engine.
It ha a carburator n a distributor in it.........
You will also find information about the differences between the Packard and the Chaika engine there.
Go LOOK!!! 01-15-2012 02:18 PM

After the post.. I went to the site.. Not an american Packard design.. highly altered. No american parts would fit.

I have worked on and built american Packard V-8's and they are nothing even close to that design internally. The company went out in the mid sixties after merging with Studebaker.. So they were post war 40's/50's technology.

topwrench 01-15-2012 04:14 PM

Bob, I know Packard is out of business if u went to that website you will see the engine design is virtually the same as whart hes got.
Ok so u worked on Packards..................I did too!
Anyway,Im just trying to help the guy!
This discussion probably belongs elsewhere
Have a good day!

Thanks, topwrench. Google gives me one result in english and 50 more in Russian, so the first time did not find.
Indeed, the topic was discussed at And it looks like the exact analogue of this engine is not.

If I am interpreting the drawing correctly the number 6 indicates the intake ports.

In that case this head has a rather unusual layout with the valves arranged IE IE IE IE.

The more usual arrangement is EI IE EI IE with the intakes paired up and the middle exhaust ports also paired up.

In the fifties all GM V8s had this layout as did Ford, Mercury, Lincoln, Studebaker and AMC.

The only company with the IE IE IE IE arrangement was Chrysler in their hemi head and polysphere head engines.And they never used the conventional wedge head.

Later Ford used the same layout in their small block V8 (289 etc) but that one did not come out until 1962.

So it appears the Russians did not copy any Detroit V8 as this valve arrangement, combined with the wedge type combustion chamber with valves all in a row, did not appear on any Detroit V8 before 1962.
With the engine chrysler has little resemblance, but no more.
Thank you all for your help. So I will weld aluminum. And if it does not, throw that piece of metal in the bushes and weld a new iron. :cool:
