Need help choosing a cam 1969 340

Jim jim suggested the 272 454 lift Crane I'd rate it around 265-368 @.006 for comparison
here's a thread
Crane's energizer cams
but Crane has 3 series of Mopar lobes
here's the shortest one
Crane rates at [email protected] for comparison it's between 253-256 @.006
Crane 2022880 253 202 113 0.299 448 H2 series .904 lifter ([email protected])
so more than 10 degrees shorter than the catalog grind and most likely fatter at .200
buy cams by sound?
