Cam Motion 5.3 "drop in" cam results, +41rwhp/22rwtq

Agreed, i tend to use displacement as a good guideline as to how to spec a cam, 4.8's up to 210 duration, 5.3's up to 220, 5.7's up to 230, and 6.0+ larger. If you start getting larger then these specs you start to lose street-ability. I went with a 214/220 .540/.535 115+2 lsa in my 5.3 and its pushing the edge of what I would have wanted for street use, and it lopes hard even at 800rpm idle and 20* of timing. I pull about 52kpa of vacuum at idle with that cam.
I use it to tow 4500-5500 lbs. during the spring, summer and fall pretty regularly so I need grunt down low and not so much in the mid-range and up top.

I had a lpe gt2-3 cam, a little hotter than a ls6 I think 207 220 570ish lift on a 118. my 2000 5.3 and was peaking at like 6200 easily revin 6600. Slowhawk suggested I advanced it 4* and just drove so much better. Brought the rpms down 5-600. Degree in the cam helped a ton. It would just blow the tires off from stand still with stock stall after to.

You pick up a decent amount with a cam that small? I was going from an LS4 cam which is a 193/193 @.050 .482/.490 lift, pretty much anything i put in this thing would have been a huge difference. lol
Buddy of mine has that cam in his 04 goat and he loves it to death. Picked up about 35hp tuned, idles at 550 smooth as butter, and has plenty of torque down low which i was shocked at.

Remember the stock 5.3 cam is 190/191 .460/.440 116lsa so just about anything is an improvement!

Our truck cams are really gaining popularity. These result serve as a great example that there is no need to "over-cam" your truck, and demonstrates what is possible with a these modest drop-in cams.

I'm wondering if my 5.3 would benefit from one of these drop-in cams??.. currently I'm running an ls6 cam, with cai, manifolds with magnaflow duals with h-pipe.
I just picked up a set of 243's that I will have milled .030 with .040 head gaskets and an ls6 intake. Truck is a '77 c10 with 3.73, 4l60e with factory style converter. Just want something with more power. Would the drop-in be an improvement? Or something like the tsp220r?

Like posted above the ls6 cam will have similar overall gains but they occur higher in the powerband. If you are revving to 6500rpm plus you likely aren't even hitting peak with the ls6. A member of this site has a ls6 in his fbody and recommends shifting well above that even in a bigger 5.7 engine.
If you want more bottom end and be able to hit peak under 6000 rpm (I have my truck set to shift at 5900rpm) then it would benefit you.

Honestly, it depends on what you consider an "improvement". Where do you want or need the increase in power? The ls6 cam isn't a bad cam for the 5.3L, and you may not see much of a difference between the ls6 cam you already have and a little drop in truck cam. But if you're looking for power under the curve, one of the truck cams mentioned would probably benefit you.
The tests that I have seen where cams like these Cam Motion drop in cams are compared to the LS6 cam, the drop in cams make much better torque below 4000 RPM. I would think your truck with a stock stall torque converter would feel much peppier and accellerate better with the drop in cam compared to the LS6 cam.
I'm looking for better power overall, but would like to see more down low as the ls6 cam is certainly weak of the line for me. It sounds like the cam motion may be the way to go if it's making more low end torque, especially switching to the ls6 intake. It will see some highway driving but rarely will I be looking to go above 85mph. Do you think I lose any top end with the cam motion cam compared to the ls6?.... And I wouldn't have to change springs (yellow beehive ls6) or pushrods (7.4) correct?

I picked up the intake with injectors and fuel rail for cheap ($200) mainly for looks.

The cam motion drop in truck cam has almost identical overlap as the ls6 cam, and a later evc event, so I would expect it to carry power well. I seriously doubt you will notice anything lacking up top. And even if you do lose a little at the top, the gains everywhere else will more than make up for it.

Sounds like this is what I'm looking for though.

Evc is exhaust valve closing event. It is one of the things that dictates how well a cam, or the engine, will carry power. A later evc will allow the combustion chamber to expell all the exhaust gas to a higher rpm, and thus carry power further.
Both of these "little" truck cams mentioned have later evc events than the ls6 cam, so my personal belief is that that the cam motion drop in truck cam will not leave you lacking on the top end, because I believe that it will carry its power just as well as, if not better than, the ls6 cam. And I am basing this assumption on the later exhaust valve closing event.
The overlap being similar between the two cams is another reason I further believe that the truck cam in question will not leave you wanting. As overlap, or the time both valves are open at the same time, is another thing that dictates how well the cam/engine will carry power.

Did you ever get the cam swap finished for the Cam Motion 10 Stage 2? In the process of swapping our Tahoe to this cam right now, as it had a collapsed lifter. The specs on the cam look good, and in comparison to what the OP posted for the smaller cam, I'm pretty excited about this cam.

Got my cam installed a couple of weeks ago. Baseline HP after the cam was 202hp. After tuning, the truck made 256hp and 310 ft/lbs. Unfortunately, the truck had a weak fuel pump, which was replaced about a week ago. It should be back on the rollers soon, just installed a set of LT's and redid the exhaust with a SI/SO 2.5" magnaflow.
The dyno was done in 3rd gear, truck is 4wd.
