Just picked up a MP 472 Crate Hemi and need some opinions

i just traded for this 472 Mopar Performance Crate Hemi and of course it's been sitting a while in the crate. My first impression would be tear it down and check everything before trying to start it. It was one of the Cummins built motors and I've heard some horror stories about them. Anybody have any first hand experience with these? I would love to hear some opinions. I've got a 6-71 BDS blower to stick on it, do you guys think it would handle that without additional upgrades? Thanks in advance.
My experience w/ 426`s are , that they are very tough in the bottom end, if they`re right. Just be sure of getting the thrust bearing lined up. But u probly know that! Small valve stems were the weakest part of them.
