cam shaft selection

If you plan on going with any lift at all you will most likely want to change your valve springs also or it will run like poo. I am running comp cams XE256H in my 318 and it has a little chop and good torque. 1000-5200 rpm, 106 intake centerline, 447-455 lift.
If you decide to go with a little more lift and want to change the springs I have a new set of Comp 901-16 valve springs that I would sell you dirt cheap. I went with magnums and don't need them.
