I don't believe that the V8's require a C service.

Thanks for the information.

Perhaps I am mistaken but the addition of a timing belt replacement on top of a B service = C?

The "B" service takes around 8 hours at an average dealer labor rate of about $140 an hour which is $1,120 plus any parts needed. The cost of a complete belt change (belts and labor) is around $2,000, so you are looking at a total cost of around $3,120 minimum, perhaps even higher.
