Stock cam or aftermarket??????

Has anyone been putting in any type of aftermarket cam? I am building a motor up and the cams trashed so I am thinking about putting something other than factory in just because it seems like the right thing to do.


Any suggestions?

did you end up putting one in? I saw on a previous thread you were thinking about it.

There's really no need, the stock cam is good to 600HP

I did not put one in. Factory regrind turned me off.

Stock came might be good to 600hp BUT, how much power could the same setup make with a different cam?

What does factory regrind mean? Wouldnt that make it smaller
Take a factory cam and alter the lobes. Yes, it would make it smaller but you can't really look at it that way. They can sharpen the curve, cut the bottom side etc.

If your going to make 600 or more horsepower then your looking at some BIG money into that motor.

Factory regrind is absolutely fine to do. Before they had aftermarket cams for the 4 valve Cobras it used to almost always be reground camshafts. Nothing wrong what-so-ever.

Ab-so-****ing-lutely true.

Diesel Innovations or Swamps is the ONLY people I would work with. Also, just because you can push a stock cam to 600hp, doesn't mean it is making power efficiently. Replacing the stock cam with a custom ground cam in the same engine will have a better power curve and most likely....


more power.

You don't need a different cam to be able to have power above 3500 on a stock cam. Injectors, tuning, IDM, valve train components, and turbo play a large role. Everything has to work together.

I will give one piece of advice.. If you replace the cam, be sure to tack weld the cam gear so that is doesn't come out of place. Once you break open the front of the 7.3 and see all the gears from the HPOP all the way down, you'll understand what I'm talking about.
