Never heard of Jet rods in a 928 application (or in any application, for what little that's worth..... Several Google results appear to be titanium rods, US made, for domestic applications. Where did these come from? What are the big end and wrist pin dimensions and C-C length?

From the GelJack stroker. I'll get you the dimensions later today.
From a stroker they are likely Chevy rods. 5.85 in length as I recall.
Holy cow, what an abortion.
Look how much they cut off the top of the piston, above the top ring.
Unless the crank has more stroke than 95.25mm, probably a 6" Chevy rod.
Oh, it gets better. Look at the bottom of the cylinder. A hole where I've never seen and additional milling at the bottom.
Oil squirter pointing in the wrong direction?
If the rods have Small Block Chevy offset, they won't be in the center of the wrist pin, but off to one side.
But the rods could be custom pieces...it appears that the width of the rod bearing is wider than that of a Chevy bearing...more like they used a 928 journal size and a 928 bearing.
Are those "ears" sticking up from the tops of the pistons or am I not seeing thing correctly, in the picture.
(I missed this earlier...these could be 5.850 rods.)
By the appearance of the oil control ring (wearing pretty flat with this few miles) and the scratches on the cylinder walls, this engine also had some "abrasive left inside the engine" wear.
So here's the crazy thing. They removed material from the top of the piston and I've been told they shaved the heads. One reduces the compression ratio and the other increases it.
I can see what's left of the valve reliefs.
Rennsport makes me feel better about my stroker efforts.

#2 is the worst. Deep scratches at the top of the cylinder. #2 cylinder with deep scratches at the top. #4 scratches near the wrist pin
