Blower motor out of a zz430

[mazspeed]

Ok I have to ask this because the shop that is doing my motor want's an arm and a leg for putting this together. I want to ask how much it should cost to take the motor out of the car, set it up for 8-10 pounds of boost and put it back together and reinstall the motor? Also the Pully system is being mocked up and done by Frank at Prodigy Customs so there will not be a fitmit issues when it comes back from Frank. My problem is that I'm being charged a ton of money for something that doesn't seem right.
From what I understand from others is that the motor needs pistons and rods and to be rebalanced and put back in the motor. That's to keep it as a 350. To do a 383 stroker I'm being told it would be quite a bit more then that. Thoughts???
