I don't like "fake drama." I don't watch most of these TV "reality" shows for that reason. If the OP has something interesting, he should say it. And post it. And maybe some video and photos. We would love to see that. But don't come here with the "I know **** you don't and I'm not gonna tell you" bullshit, OK?

This thing could be VERY interesting, if you make it that way
 
Well, I confirmed it with Larry Shepard hisself. The guy's tellin the truth ......at least that SOMEBODY has the blueprints from Larry. Now whether it's "this guy" or not, who knows? But evidently someone does and is supposedly working on more than one of these engines. That was straight from Larry.
 
Yeah I get that. So lose the mystery. Just come on and post something about it. I would be interested along with lots of other guys.

The OP made his own bed here on this. I did not sell him one
 
Did any of you notice that the front and rear "Intake Valves" go to the water jackets and not combustine chamber???????

Oh, fun. But not so horrible. Assuming they're not point clouds.

Stl files can make a decent solid (sometimes), which can then be used to make a decent parametric part. Been down that road. Sadly, it takes building a whole new part using the Stl as a guideline rather than using it as an actual basis for a part. Can still be done though.

Do you have any original drawings? A layout with intended angles and spacing for things like bores, lifters, and cam tunnel height could help guide things versus just trying to reverse engineer existing parts, which usually winds up at least a little off the mark..

Its possible to get some. There is a guy who has em and will have to give him a call to see if he can dig them out.

Those aren't water ports. They're intake ports. The heads each have six siamese intake ports in the middle and one on each end for a total of eight intake ports per head. They also have eight exhaust ports, but the split comes into one outlet just before the headers.
 
Here is my silly question.

If these Hemi heads have dual overhead cams why couldn't you put them on a 440 block?

I know years ago somebody came out with a conversion Hemi head to put on the 440 and 383 blocks. I would assume that the head bolt holes are different. Especially since the Hemi has the extra Bolt hole on the top of the cylinders. Basically what I'm saying is rather than going expensive a Hemi block wouldn't it be cheaper to use a 440 or 383 block 2 get this all set up and working.

Gary Ostrich and Charley Malyuke did that in the 70's

Thanks, I did not see what the intake manifold for it looks like. Seems like images about this engine are rare indeed.

They sure are.....plus it's exotic as all hell too which doesnt help. lol

it was pretty funny
in fact, i tried to start watching it online the other day, but i couldnt find a decent site to watch it on, so i passed on to the next one
 
After consulting multiple professional reverse engineering people, because of money I will have to figure out for myself the painstaking process of recreating the scan data of the head into something usable for a foundry to cast. Will update in a year or so when the model is complete, haha.

If you need help with the 3D modeling process, I can give you a hand! I'd love to see this become a real part in the near future, so lemme know if you need more hands to make less work.

Slight correction.

This type of scanning creates point clouds, not STL files. STL files are created _from_ point clouds and are only a shell, not a "solid" nor are they any sort of CAD file.

Still, if the point clouds are of significant resolution, they could be a very good basis for taking measurements and creating a real model from which something would be machined.

Depending on the software, some optical scanners go directly from the point cloud to a generic solid or STL (which are surface only). Most cad I've dealt with can make a solid from a decent quality STL pretty easily though.

Way back in the day if we reverse engineered something, we had to use CMM data which came in as a raw point cloud. It created a lot of extra mouse-miles when starting from that. Some CAD programs though(like CoCreate) could actually build a decent curved surface from a point cloud. For other software (ProE, Solidworks, Inventor) we wrote some Macros to create meshes as reference geometry.

It's been a while since I haven't gotten at least an STL surface output from a scanner, but if points were the output I expect there's more tools available these days to speed up the process of generating a solid.
