Seems like it does since they are both rated at 300hp.
I'm just saying that with the dinky cam Mopar put in the 5.9, I would guess it wouldn't add more power to change anything out. Roller cam or not. I just doubt that it can make 350 hp without swapping the cam for something that actually has lobes on it.
The 350 on the other hand seems to have a decent sized cam and added 30 hp by swapping to the Vortec heads.
Note that in the test above that 5.9 made 350+ hp with a cam that was similar in size to the one in the 300hp 350 you mentioned.
