Carb and Intake for 5.2 Magnum

I also found oddball specs that advanced the chit out of that cam in a 5.9. It had a lot of exhaust duration on it,, so they could get away with that, but according to the specs I found, the overlap period was all crossed up. I found a lot of internet hoopla about these Mopar factory Magnum cams, but no one would commit to hard numbers so I gave up looking.

When I backed that 5.9M cam up on paper, it looked suspiciously like the 5.2M cam. Again, I found nothing but whispers on the wind.

IMO, what ever cam was in my 92 5.2MDakota, that thing did pretty good on gas. When I replaced the timing gears I just slammed it in dot to dot. I wasn't thinking that many years later, it might be valuable information, lol.
My old MP catalog lists two cams for electric fuel-pump engines;
P5249549 at 260/264/109 and lifts of .458/.467 lifts, no .050 numbers; and
P5007551 at 272/278/119 and lifts of .467/.482 >050s of 208/216
Yes that 119LSA looks real, cuz it shows up in the mechanical pump engines as well.If it is, it will be horrible on gas.
But the smaller cam should do well on fuel. In at 109 the Ica would be 59* for lots of trapping, and the powerstroke comes to 119* for lots of extraction. The overlap is 44* and well-centered so reving to 5500 should not be a problem.
The only unknown is the .050s, which judging from the other cams in the catalog that do have .050s, the Mopar cams have really really long accelleration ramps; read tiny, .050s for their advertised, I would suspect that small cam has less than 196* intake duration at .050. I wouldn't buy it.

The catalog also lists 4 cams for mechanical pump engines

IDK if any are still available
