I'm considering on doing a mild cam to my 7.3. Anyone know if there is an aftermarket cam available without having to get my pistons cut?
Matt at Gearhead does a stage 1 and stage 2 cam. Neither require piston work.

Outlaw diesel has cams don't know how well the work but the stage one cam don't require valve reliefs cut in the pistons

I suggest you talk with your engine builder. I deal with a guy that designs CAMS for NASCAR and he has looked at a number of CAMS available. His comment was that the stock CAM is VERY good and little can be done to improve it. He said the only way to improve the CAM is to design custom push rods and valves to work with the new CAM profile.
This is why most have seen a loss in HP with CAMS.

But is his comment based on his NA gasser experience? What experience does he have in the turbocharged diesel field?
And how would he change pushrods and valves? I'm trying to understand that part and it doesn't make any sense. I could understand lengthening a pushrod to compensate for a reground cam. However I think Matt has stated elsewhere that the lifters will pump up enough to compensate for the amount of lift he is able to get, and it's enough to require flycutting pistons in his stage I and II, which kind of leads into changing the valves. I'm assuming this means valve stem length in order to get more travel, if we can already get enough travel to require piston cutting, how much more is needed?
