470 hp? Then there is the brake upgrades,rear end self dismantling and all the tires needed to playing with the fun pedal.
from what i have been reading about BP is they are well built.
Which i would consider dependability. There is nothing worse than a driveable hot rod that is constantly broken down.
and right there is the project the op says he wants, upgrading everything else to handle the power of the crate motor. plus swapping/upgrading the running gear has much less chance for catastrophe than building a motor for the first time.
