Viper where run by Oreca.

Chrysler believed that in order to adapt their car not only for North American but also European circuits, the French racing and engineering firm Oreca, who had many years of experience in sports car racing. Oreca would construct and maintain the racing cars in their shops, as well as run Chrysler's official factory teams in Europe.

Although Oreca would construct the cars, key elements would come from British engineering firm Reynard Motorsport. This would mainly consist of the construction of the car's basic chassis and other integral parts before they were shipped to Oreca for assembly. As for the Viper's engine, it was ideally suited for competition at the time due to limits of 8000 cc being just beyond the Viper's 7986 cc. Modifications were therefore light for the 356-T6 V10, with concentration on redesigned intakes for horsepower and reinforcements (oiling modifications) for endurance.

off topic: I have a '08 race viper (SRT-Competition Coupe) brand new engine in my shop waiting to be custom build ( custom made main caps, ARP studs, crank, rods, pistons, intake) for boost up with 4.2 L twin screw.
And then to be installed in '70 Bee. How many knows that the engine is Ilmor Marine boat engine?
