Diskovod Hehe. The crowds start to move.

It was me long time ago to start that topic on the PackardInfo website.

So I thought, some one has to offer off-shelf parts for that ZMZ V8 (truck series) engine. Let it be me then.
Few years ago I felt into developing suitable performance parts. And hopefully, I'll offer some of these pretty soon.

One of the main parts to go is a 2/4-bbl american carb intake manifold.
I'll be doing some prototypes soon, then I'll discuss the design with the aluminum casting factory to maintain lower costs.

P.S. I'm also developing a range of billet cams along with Steve from LSM Engineering from Michigan. Yup! Those who are in the scene know his stuff better than me. First bunch of stock-parts-friendly lumpy cams should be ready this winter. Figuring out cam profiles now...
Also I'm doing a kit on liners to switch to SBC stock 4 in bore pistons, because the head chambers were designed to work with 102 mm bore. In stock form it has a 92 mm bore and intake valve would interfere the liner at about 14 mm lift (0.551 in). But people usually shave off 2 mm, so it's only 12 mm (0.472 in) of ideal lift left! Which is no good, because you have to do some gaps, "what if" and etc. The 4 in bore would let the valves breathe freely.
Recently, it started as a Darton MID-stlye sleeves, but I had to design the sleeves myself, because Darton guys weren't willing much to help without seeing an actual engine. So now it's my standalone design, with top&bottom fixture and low price, plus some optional features.
P.P.S. Not trying to trade here, just sharing some information about my progress.

Augusto Comrade, don't waste your time altering the manifold, just install a turbocharger and your engine will come alive big time, even with the small stock carburator, dont grind or file anything, just tune the carb and the ignition for the new boost pressurized engine.

do you guys have in Russia the Mercedes Benz diesel OM352 engines? you can use the turbocharger from this engine, it's the perfect size for most small block V8's and at least here is very cheap $450. if not, use any turbo from a Kamaz diesel truck.

cobalt327 What goes where the arrows are pointing, below?

MTide 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.

topwrench 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!
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.

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!!!

MTide 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.

topwrench Go to youwill find the engine there

MTide oops, ok.
Now through the gallery.

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

MTide 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.


01-14-2012 10:27 PM
MTide 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.
