What about this cam?!

[andben]

Hi, I think I have this cam in my 440. Very nice torque.
Can someone tell me a little about it? I dont know so much about cams...

The Comp 280 Magnum is a nice cam....it'll want 2500 stall and 3.55+ gears for best performance.

What differ the Magnums from a "normal" cam? I have 3,91 and 2500 rpm stall converter.

Someone told me this cam is like stock 440, is that true or is this cam more agressive?

Looks like a very good cam. You find more data here:

Seems that original 440 cam opened intake @ 19 before TDC, this one opens @ 34 before TDC so more duration than original.
Hemi original was  @ 30 before TDC

The factory 440 magnum cam was 268/284 with .450/.458" lift. The comp 280 grind is ground more agressivly with .480" lift and with duration at .050" at 230 while the factory cam is at 208/221 @ .50". So it is a couple of steps above the factory cam.
