Not sure, bad math? You have any idea what cam it could be?

How did you get .492? Subtract base circle from lobe and multiply by rocker ratio for valve lift.
(1.578-1.272)x1.5=.459

TT5 is correct on the lift of this lobe, but you need to measure another lobe next to that one for us to even be able to guess what it can be...

We need to know if it's an intake or exhaust lobe...

This is my best guess with the information that you have posted so far:

Duration 268/272, Lift .450/.455, Chrysler, 273, 318, 340, 360
