My truck is pretty strong throughout the whole powerband. A stall converter is ideal for all vehicle's if you ask me, especially in a 4wd. The engine will not bog, and that's what you're looking for. With a stock converter my 212/218 does not have as much torque from idle as a stock cam would, but w/ the yank, at 3000 rpm you'd have to be in a serious bind to bog the motor-something would probably break first. IMO, you shouldn't go bigger than the 212/218 b/c you will put your power in the 6000+ range. Again, I would put the converter first.

Mr. Sandog

The application really has to be known before making a recommendation. If this guy with his 4x4 has a habit of attempting to go through mud bogs at top speed, then a new cam with a 2600-3000 stall is great. However, if he goes 4-wheeling in a traditional manner, which could entail 1 mph crawls through trails, and over rocks and boulders, he'll be royally screwed with anything over a stock converter. A slip of the wheels, and he could end up stuck, or inverted.

So I don't think your statement holds true - that a stall is good in 'all vehicles.'

I've been considering a cam for my truck and have been playing around on an old desktop dyno program with some cam profiles. I'll say that a properly choosen cam will increase power thru the entire usable powerband.
Of the cams I tested, the Comp XR259HR(206/212) showed the most TQ at 2000. Other cams with 208/216 and 210/218 showed slightly lower TQ at 2000 but seem to quickly make up for it in the mid-range and at higher RPM's, while still matching or bettering the stock TQ at 2000 rpm's.
Now this was a make beleive motor on a computer program, so I can't say how well they will work in real life.

That sounds pretty accurate, Silver...

There was a pretty in-depth "low duration, tight LSA" thread in the LS1 internal section... There were a few of us out there looking for torque cams. What you stated above, sounds a lot like what another member also found...

COUGH:listen to big tex.

Mr. Sandog

Tex also said, that he did NOT say that no bottom end would be lost (which I take to mean that some bottom end WOULD be lost).

I do believe that the guy who started this thread saying that he wanted to PICK UP low-end torque. This tells me that the 208 cam is not for him.

Point is, a tight lsa, short duration, fast ramped camshaft with as little overlap as possible is going to be a great choice for his needs.

Mr. Sandog

Not if he wants to gain torque and keep his stock TC. Not just any 'tight lsa, short duration, fast ramped camshaft' will do. Anything over a 206 will cause him to lose low-end.

REALLY? please tell me how you know this

Mr. Sandog

With a 6.0L, maybe not. But with a 5.3L, yes it will. Futral, Cam Motion, lots of other people who know their stuff, the other guys in this thread, etc...I believe them.
