I stumbled across the following last week and was amazed I had never heard about it previously. I would love to see any pictures out there of these cars with this unique power plant and hear more about them.
I believe the following originates from a post on the viper alley forum by a user named Exotic Engine Dev.
"Only one place on earth, one time a year do 260 entries take the green flag for 24 hours of racing. The 24 Hours of Nurburgring in Germany is the ultimate test of team, man and Machine. Two Dodge Viper GTS-R race cars took the green flag. The #3 Zakspeed Dodge Viper GTS-R powered by a very unique Exotic Engine Development V8 / 10 engine started from the front row. The #33 team Zakspeed team car started in the twelve position. The # 3 car driven by Peter Zakowski, Sascha Bert, Patrick Huismann, and Hans Peter-Hypertnieder started from the front row and ran in the top three for 15 hours before retiring with a major gearbox failure. The #33 Dodge Viper GTS-R V8 / 10 of Christopher Gerhard, Dirk Riebensahm, Werner Mohr and Peter-Hans Huppertnieder finished in the third position overall, first in Class SP-8. The #33 car finished the 24 hour race traveling at a top speed of 295 KPH and covering 2415 miles. Both cars are powered by an Exotic Engine Development V8 / 10 with JM Striker Cylinder Heads. These engines are 6.2 Liter V8's built within the Dodge Viper GTS-R V-10 architecture. The front two cylinders are not functional. Very unique, very powerfull and very reliable endurance racing engines.
The engine is basically a small block V8 built within the GTS-R V10. The crankshaft is built as a V8 with a shaft only passing through the front two cylinders, Same with the camshaft. No rods, no pistons, valves with springs to plug the holes. There are plugs in the lifter bores. The engine is 6.2 liters (378 cubic inches). It makes near 650 horsepower at 6900 rpm. Engine management is Motec. The engine has JM Striker race heads. These heads are good for an additional 40 horsepower on this engine. We have a little more development planned to improve torque and fuel consumption.
Everybody asks why? In the FIA GT or FFSA GT we have to run two 33.4mm air restrictors on the 8.0 liter V-10. Power falls from 830-850 HP down to a meek 580-620 HP. The rules state that we must use the original cylinder block, but it does say we have to use all ten cylinders.
There are no rocker arms on the front two cylinders (1&2)V10. Peak power is at 6950 rpm, they shift right around 7100."
Here's a video of one of the cars:

I even found the car on the Forza Motorsport video game and sure enough it has that V8 sound just like the video.
Anyone else have any association/history with these engines?
