Good. The manufacturer is Camshaft Machine in Illinois (they may have relocated). it is a "generi-grind" sold by several vendors, including Melling, Elgin, Edelbrock, Mahle, Wolverine, etc. (all marketers, none are cam grinders). Currently, CMC "soes" most of the flat-tappet hydraulic V8 grinds for MOSTcam sellers including Comp and Crower. Of course, Comp, Crower, Lunati all supply their "own" masters and the grinds are propietery.

This is a mild performance grind. It should offer a pretty smooth idle and will be fine with a "stock" converter. For a little better top-end performance, use "Z/28" (or similar) valve springs. NO "rotators" on the exhaust valves!!! Stick with 1.5 rockers. If you do upgrade the springs, a 1.6 rocker on the exhaust "side" will pick you up some performance. Most modern grinds are "dual pattern". This one is a "single" pattern (both lobes "look" alike).

Comp's old 260H grind is CLOSE. It's 212 @ .050. It has an LSA of 110, though. The stated power range for the Comp cam is "1,200 - 5,200". I suspect this cam would bring the power "in" a tad sooner (the LSA) and not be quite so "peaky" as the Comp, "spreading" the power to the same upper limit. Important to note, differences in performance between the two would be minimal with a grind this "small".

For a 400, this would be a "torque" grind, probably running out of "breath" closer to 4,800 than 5,200. What exactly do you want it (the engine) to "do"?
