T603 engine designed by Julius Mackerle.
http://www.eurospares.com/graphics/engine/...searcheable.pdf (thanks jd74914 )

By raising the camshaft far above the crank in the valley,the rocker geometry for the exhaust valve is improved,perhaps making possible the use of common rockers throughout.
Note the hemi-like chamber and wide angle canted valves.Like the VW/Porsche and Corvair,the bore diameter is restricted by the cylinder head studs.
A considerable amount of weight savings would be realized by adopting LN cylinders.
I believe the crank is a conventional cross plane and at a small 72mm stroke,there may be plenty of room for a much larger stroker.

The discrete lifter-blocks allow replacement roller-lifter and barrels to be installed for low friction,high rpm operation.

Tatra 613 unfinished project - Diesel. Unique project of rebuilding the engine T613 (aggregate) on diesel variant. At the end of the 70th century originated minuléto years so far unique project for rebuilding the engine on the T613 diesel engine with direct fuel injection into the cylinder. As a base engine was used T613 (model E) production year 1977, which had traveled 20 thousand. km. The creation of new pistons with a semicircular shape of the bottom of the piston has been redesigned combustion chamber cylinder heads were modified cabinets cam engine was devised to drive fuel injectors, all this was preceded by a complex formulation of models later casts, followed by manufacture themselves cast as pistons and various components, from which the formed parts for driving the injection pumps, produced with a special injector, it was necessary to devise and make special threaded shaft for installation into enclosures injectors cams and cylinder heads. further information only serious and technically savvy candidates. This project is a testament to immense creativity and skill of the Moravian-wise and because the owner of this concept does not want to make this engine ended up in scrap, looking for this very technical and design an efficient, technologically savvy real enthusiasts Tatrovaks heart for engines Tatra, which this project dotáhnul to successful end. The owner of both the engine and the entire project, originator of the idea itself is ready to provide serious, but it really only serious candidates all technical and knowledge support to complete this project successfully. The owner, however, asks dealers and speculators, who, on this project, they just want to earn without it without touching anything, so this video in any way responded.

P.S. The video is mistakenly stated that the year of manufacture of the engine is 1997 correctly's 1,977th

Well,someone out there in the hinterlands of the E.U. must have a handle on these lightweight V8s.
If not,an Opportunity exists to meet the demand for the unique small 4+8 zylinders.
Other than auto applications,a kitplane aero app may move a few of them.
Simply gather as many pieces that you can and put up an Ebay/Samba for sale sign.
I'm somewhat surprised that a VW/Porsche fan from the Continent hasn't considered a powerplant of such attributes.
A further question regarding the dimensions of the bore spacing and cylinder stud pattern remain unanswered.
Scaling a photo may derive a close number,but only close.

Judging by the positive reaction on virtually every blog and posting for the last decade,a surprising number of wrenchers would like to have such engines.
And to think the Ford V8 of '32 was it's contemporary.
In hindsight now,it's no surprise that the ArDun head for the Fhead Ford used a similar,independent latest big breathing pentroof/crescent design.
An aftermarket to develop hotrod parts for the engine never happened.
Rollertip rockers,rollerlifters,modern valves,all the things you would do to your aircooled VW,Porsche,Corvair,Hirth,Rotax...
I haven't seen anyone other than the factory turbo the engines,so,you could be the first.
Could be fun.

Weird. The front is definitely five-bolt, the rear looks like four-bolt.

EDIT:
Looking at the pics on the website linked shows they were all five-bolt. So the four-bolt look must be an illusion. Probably the "uneven" part of the bolt pattern (where it does not match with the eight spokes) is out of sight on that rear wheel.

Sure,a great idea,rather than purchasing an off the rack auto,make a custom.
California is a goldmine of automotive design/build talent.
Start like we all did,scratching our "Lambo"with a pencil on the back page of notebooks.Mockup scale models and when the results please you,move to full-size mounted on the recipient Fiero chassis.Beat alloy panels into shape over wooden bucks like Bertone or layup into a mold pulled from a buck.
So yeah,a huge effort is required,and at the end you may have something like a Bradley or (hopefully) a Frua 914.I suppose that is why I can appreciate the results
Eberhard Shulz attained with his Imperator 108 in the '70s.A verbatim replica of others work would not suffice,so he designed and built his own.An achievement like that requires more than a passing knowledge of design and manufacture.
It all starts with an idea,so determine what your quest is then blaze a path.

Fat tires-check.

pseudo f40-check

As you observe various auto designs are you able to percieve rust and or dents
from a distance of 100 yds?Sure,so it is entirely possible to detect the shape of
the fenders of a 911rsr.Expedient measures to cover the tires range from this
to the shapely splined flanks of the 914.
The necessity drives the invention.

The idea of a low powered runabout with a mid mounted transverse engine was a demonstration of technology sophistication.

The engineering that went into the stamped steel chasssis produced a rigid crash safe exoskeleton.

All that's required is a dieman to create repair panels for the chronic rust areas.
Then add lightweight power for a decent mid sportster.
Different crash safety requirements,the reason for the 914's cancellation.

The more I more I consider the cylinder heads of the 4cam 613,the more I'm inclined to think they may fit quite easily onto a Corvair shortblock.
