So how stout would that beast be? You'd have to keep softer piston rings in that engine to make it last for any decent amount of time wouldn't you?
Would depend if they were going to run liners or not
If not they run a coated piston much like a Porsche 928

I thought you mentioned something about the coatings on the skirts not lasting very long... Is this a different coating than that?
Very very different type of coatings 
The stuff I use is just a thin coat of Moly to prevent galling while everything is tight and new theirs is an actual working coating that resists wear and provides a dissimilar surface to prevent the materials transferring and seizing.

I'm not even sure what scale it is as I'm not familiar with the Matss spindle and there was nothing else to judge by.

ill take one that comes to 6 ltrs, bolts to an r154 7m bellhousing, uses a 9:1 CR and has a 32v quad cam head. that is...after i hit the lotto
WOW, I don't even want to think how long it takes to design something like that on the software.
or even worse, to plot the cutting course for the machine...
whole time I was thinking "ok wise guys, how are you gonna cool it?" open deck block is the only way to do it...

That was sick. what was it doing to the cylinders just before going into the water jackets?
open deck block? they couldnt machine water jackets into it?

I don't know if nickel silicon carbide is economic enough for the common folk like the you's and me's. Well... if you can afford a CNC V8 block of any size, you can probably afford to have your bores nikasil'ed. That stuff lasts forever it seems, in motorcycles, you guys know if it is used in any automotive applications, I think some Audi and Veedubs might have it.
Nevermind, a quick google, and I found this. http://www.bmwworld.com/engines/nikasil.htm slide down and read history.
