72Swinger that's absolutely correct. Its pretty much out of the mopar engine book in the back where the break in section is....Graduated acceleration tests. I have actually broken in 2 engines with the car on the trailer. One at 2am at LAX where its is noisy all night. One at the race track. But I think maybe MuuMuu101 may be referring to some of the mechanical aspects elsewhere on the car not being ready yet, After all the car has to be dependable.
