Thats a fantastic budget camshaft! We used it in my brothers first small block. It shifted at 7200rpm with a 3.79 stroke. It also had box stock edelbrock cylinder heads and an M1 manifold. The car went 11.09 @ 118mph with that cam. With a 3.58 stock stroke 360 it should be more like 7400-7500 RPM with the similar parts used. It sounded great as well. Im not sure how well it would work in a heavy vehicle though.
10.53 @ 125mph. 1.37 60 foot. Caltracs and Monoleafs, AFCO shocks.

In the MP book they say to use .850 x advertized duration to find approximate .050 numbers for cams in the mild range. It works pretty good for the most part up to the MP .590 cam For me the MP cams below matched the .850 math .484 @ 284 = 241 @ .050 .509 @ 292 = 248 @ .050 .557 @ 296 = 251 @ .050 and actually measured the same or very close. But the MP .590 didnt .590 @ 312 = 265.2 @ .050, it actually measured 272 @ .050 Reguardless, I like the All the MP cams above, the MP .557 is a good one. My measurements above were on the BB cams only. I assume, the SB lobe profiles would be the same. mike

thats a bunch more RPM than that cam likes
my 69 dart 2970 lbs W-2 318 only turned 6,700 RPM to run 10.9s @ 121 the same cam in my 360 liked about 6,600 RPM ran 6.6s @ 104 1/8th its a nice cam makes good power for what it is and is verey mild manered if you want to run it on the street
