I've driven a bunch of these and although they are nice, I'm just not that impressed with them.
The V10, both aluminum Viper and truck cast iron share the same bellhousing bolt pattern with the Cummins diesel. So automatic overdrives are available but the bellhousing is huge in comparison to a 904 or 727. I'm sure it could be put into an A Body and probably has. I've entertained the idea of fitting a cast iron truck V10 into an A Body but the lack of aftermarket performance parts is an issue. Some Viper stuff works and there are some truck performance pieces available like cams and blowers.
They are torque monsters that don't rev very high though plus they aren't light. If I was going to put a truck engine in a car it would be a Cummins diesel.
