Mopar P4452761 Camshaft

We tested that cam for Direct Connection back in the day
268 degrees is the same as the 440 Magnum cam but this lobe is fatter even though the lift is about the same (so can use the same HP springs and no machining)
The Magnum has much longer ramps so there is no clickty clack during the warranty period
the lobe centers are obviously squeezed which will give more low end but more emissions
What we found is that this cam is about as big as you can go in a 440 with the stock HP converter and 3.55 gears
anything bigger like the 272 and especially the 284 costs 60 ft times without a converter and even a gear change
DC was never big on .050 - for years never published

"I think other modern cams would be a better choice. Like comp XE268, or Lunti 268."
Modern LMFAO HE268 is a 40 year old Harold Berkshire Chevy grind
Lunati Voodoo is a little later and was designed by Harold for Chrysler not Chevy better choice or you can go a size shorter with same lift as HE268 if you are not running as much compression
