I have read some dyno's of LS6 cam swaps into 5.3 trucks. It push's the power way up the rpm range.

I want the power to tow and want the power/torque pulled down lower in the rpm range.

Can you advance the LS6 cam to accomplish this?

All the info I find tells me that the cam is retarded about 3* with a ICL of 120, so if you advance it and set the ICL to 114 it would be worth a try if you already have the cam. If you don't have the cam then don't get it; you can do a lot better.

You'd be a lot happier with a Lunati Voodoo #20540710 (212/218 113lsa+4, lift .531"/.531" ), or any very similar cam from Crane of Cam Motion.

Yes you can advance it

Put it back to zero?

Any P to V issues?

Why would you invest in an adjustable timing gear to make this happen when you could just get a better custom ground cam made that would make more power everywhere over an LS6 cam?

Because I want it to run like a stock truck but have more power everywhere.

Used LS6 cams are a $100 all day long, no idle issues. The cost of the LS6 cam and the timing set is still less than the custom grind by itself.

I can buy the cam, timing set, all the gaskets for less than the price of the custom grind................that's why.

I really don't see the LS6 cam being much if any upgrade over the stock cam(even advanced) for your intended purpose. IMO, it sounds to me like you already made up your mind about the ls6 cam, so give it a try and tell us how well it works out for you.
BTW, the ls6 cam might be you least expensive choice, but it's not your best choice.

Do some research, I have. On a engine dyno in a 5.3 with a LS6 cam swap gave an increase of 40 hp, for a $100 thats a killer deal. That same test on a stock 5.3 with manifolds...LS6 cam, catback, CAI, 4 degrees timing was a gain of 60HP and 25 ft lbs.

Not a thing wrong with the LS6 cam. Because its not the "flavor of the day" does not make it a bad choice.

I want pulling power, I want a quiet stock idling truck. With this cam, a catback, tune, CAI .....35-40 to the wheels in hp and 20 in tq should be achievable all while driving like a stone stock truck. I have no desire for an ill idling cam hopping truck with an unusable powerband.

I am not after speed, I am after pulling power and driveability. The LS6 cam is a proven performer, will run 150,000 miles on a $100 set of springs.


I want an everyday useable truck that I can pull a car on a trailer with, drive like stock and make about 50-60 hp with a little effort, the LS6 cam should fill this request. I don't need a $400 cam to do what I want to do IMO.



This post was made to see if it was doable to advance the cam to bring the power down into a more truck pulling rpm range with no piston to valve clearance issues, seems as though I can.

Thanks for the input though.

I am very interested in your possible results from this. I have always liked the ls6 cammed 5.3 except for like you, it makes the power too high in the rpms. My truck is a daily that might get ran a little hard but that doesn't mean I wanna run it to 6k to make the power.

Driving like stock otherwise is a huge plus to me. Also no need for a bigger stall with it either.

you will need a tune ,consider a mail order tune from Frost.look at comp cams 54-408-11,or 54-455-11.both work with a stock converter ,and are good for towing.

I figured it was about money, fyi I had the same idea and stuck an LS7 cam in my LS2 tbss that had a CAI, tune and electric fans made 344/376rwhp...wanna take a guess what it made afterwards? Same hp and a loss of 15ftlbs, it did make more power from 5500+ though and that was only with a change of ~7* IVC

I'm curious to see your results, but from what I've seen the gains are 30hp from 4k+ which is not where you're wanting to make power from my understanding. The IVC of the stock 5.3 cam is ~11* earlier than the LS6 and that is what is going to determine powerband. You're sticking it in a smaller motor that was designed to move a lighter car and carry power out to 6600rpm. Not sure how much you plan on advancing the cam, but when you do it opens the causes the EVO to be earlier which is not what you want for building low end torque. Hope this helps, good luck and happy 4th of July!

I am all about money vs gains, this makes sense to me to do this cam. Planning on a 2-3 degree advance to move the power down in the rpm range.

If I could find a cam that would be DEAD silent and do what I want I would consider it. I want it to drive as it rolled off the floor but have more power.

I want to have the power of a 6.0 liter without swapping.

Would love to see some numbers before and after your swap. I find this to be a very interesting set up.

My opinion is based off of your stated use for the LS6 cam(towing). If you did a even a little research you would see that the LS6 cam doesn't get recommended as a truck towing cam, there's a reason for that; its not!
So don't get all bent out of shape, because a little constructive criticism hurt you feelings ; that was not my intent!
For you intended use I'd at least go with a 01 LS6 cam(207/217 .525" / 0.525" 116 LSA) and advance it about 4*(112 ICL). It has a little more intake duration, and slightly lower lsa which should get you closer to what you need than the 02 and up LS6 cam.
I do wish you the best of luck with your build, let us know how it turns out.

Well don't want to get into a pissing match but one guy that has a mustang that races a lot he put a z06 cam in and his car only picked up a 10th in the 1/8 mile,, and this was in a 100,000 mile 6.0 motor,, Ive had already bought a cam and springs then found this out,, just not worth the time to use the z06 cam for a tenth in the 1/8 mile...

Your boy didnt do any research.

The LS6 cam was designed for a 346 inch engine, when putting a cam like this in a larger engine rarely do you get anywhere.

In the reverse, when you take a cam like the LS6 that was bigger than the LS1 cam in the same CI engine, it picks up power. The LS6 cam in a 5.3, same thing...because it's bigger and the engine is smaller than it was designed for. 405 hp LS6 cam is usually good for about 20-30 to the wheels in a LS1.

Advancing the LS6 should get it to pick up some torque and lower the hp in the rpm range.


I will look for a 01 LS6 cam, nobody wants those.

what are your truck cam specs ...I think u have had it right all along.

And I will sell u an ls1 intake for another 15 hp from low rpm to mid.lol
