I don't know what the going rate is for the V10, bad thing is it is really a very good motor so there are not a whole bunch of folks replacing them plus only about 10% of SD got the V10 so the demand for a pulled motor is low. You might consider selling the whole truck and find a 2003-2007 with a dead 6.0 to swap instead. I sold enough parts off my dead 6.0 to pay for my 12V. And I still have the heads and some other parts laying around. If you can find a 5 or 6 speed truck that would be the least expensive. Just a thought.
