From allpar:
Unique features of the Viper version of the V-10, versus the V10 truck engine, included a low-profile cross-ram intake with dual throttle bodies, the manifolds, oil pan, heads, and accessory drive; the compression ratio was raised, the pistons lightened, the maximum engine speed increased, the valves enlarged, the rods and crank strengthened. In the end, few components were shared with the truck engine.

I would like to know what these few components are. Is there a good place to call to get information like this straight from Dodge? The tech guys at my local dealership don't ever seem to know anything useful....
At the time the Viper was being prototyped, Chrysler owned Lamborghini. They had Lambo cast the engine in aluminum since they had experience with long aluminum V engines. Since they didn't need the weight savings, nor does aluminum hold up particularly well for a heavy duty work engine, they left the truck version cast iron. Plus this was cheaper. Found that thread, give this a read:
