440 camshaft

Hi all
I took a 440 engine apart and the camshaft has purple written on it and on the back it is stamped P4349449. This has to be a Mopar Performance part yet there is no listings to tell what the exact lift and duration is. Does anyone know how I can cross reference this part number to find out the lift and duration? Thank you

P4349449 280/280 234/234 .474/.474 int c/l 110

Is the P4452993 a supersedes number of the P4349449?

( which is stated as 238º @ 0.050 duration but being really 234º as somebody measured and posted around )
