6.0 cam recommendation

Looking at swapping a 6.0 in my 02 1500 Silverado, the 5.3 is a joke no torque.

Plan is to redo the stock bottom end....9/5:1 ??

I will port the stock heads, intake TB

3.73 rear end stock tire size
Exhaust will remain stock for now so its smog legit and quiet.

Focus is on nothing but torque so I can tow. Dont want a lope (for once).


Was thinking 208-210 on the intake or?
Want a gentle ramp that will last 100k not a ton of lift to wear the guides.

Have access to a Z06 and LS3 cam but hear they are lazy on trucks.

stock converter for now dont want to go down that path.
Down the road may sneak headers on if htere is an EO?

Would ls7 exh manifolds work?

Thoughts?

Re: 6.0 cam recommendation

Don't go with the LS6 cam. It doesn't kick in till after 3k, you'd be miserable. Before I had a stall it was like waiting for turbo lag or vtec to kick in.

I realize there is no replacement for displacement and I am running a 6.0 in my chevelle / daily driving a 5.3 in a yukon.

Have you gotten the 5.3 tuned? You wouldn't believe the amount of power GM left on the table in the tunes. I understand they had to meet emissions, multi-faceted temp extremes, etc, but a tune does make a considerable difference in the drive-ability of the truck. Ramp in more timing, pull fuel as they run rich, nets some solid gains.

You'd also be surprised what a converter would do to wake up the truck. 5.3s are strong but getting a slight stall converter with a high STR number makes a HUGE difference in the bottom end feel. Even if it wasn't enough it'd be a great platform when you went with the 6.0.

As far as the cam I'd contact Tick Performance or Texas Speed Performance to see what they'd recommend. Not sure how tight the emissions testing would be for you?

Re: 6.0 cam recommendation

interesting ,thanks. Converter does feel a little on the tight side will keep that in mind.

Re: 6.0 cam recommendation

I think you are right on track looking at 208-210 intake duration at .050. Cammotion would be my top pick. They are well known for their excellent cam cores and gentle lobes. Something around 210 intake duration, 6-8 degree exhaust split, 114 LSA, and .550ish lift at valve would work great. Call and talk to Bobby.

Re: 6.0 cam recommendation

Sounds fine id think..
For once...build something that makes sense and probably works...looking for ward to torque!

I was reading some guys stroke their 5.3 to 383 using a 4" crank

What is the valve size limit on this bore?? May be another option so I dont have to spend 1k on a block

Getting my direction all turned around, not up on all the lsx stuff.

Any suggestions??

Re: 6.0 cam recommendation

If doing the 6.0, see what heads are on the 5.3. If they are 862/706 swap them on the 6.0. Even with the smaller 1.89 intake valve, the chambers are small and will up the compression a point and should make good power.

Get one of the Summit LS truck cams and reuse the lifters. The stock manifolds are supposed to flow pretty well, worth a try.

Im running the 862 on my 6.0...upgraded to a .660 double spring, better pushrods, ls7 lifters and trays. Stock other than that. But I went with a bigger cam. Havenít ran it yet, so jury is still out.

Re: 6.0 cam recommendation

706 heads, originals
I worry about the quality of aftermarket cams....Id get some gm lifters as I want at least another 100k out of this

Probably keep the lift under .550 I dont see the benefit of going higher its a heavy truck

The summit cams are nice. LS7 lifters are cheap...

Get the summit truck cam, 862 heads and LS7 lifters. You can get those heads at the junkyard for cheap and clean them up. Summit has gaskets and cam kits on their site.

Re: 6.0 cam recommendation

Interesting to hear that the LS6 cam Is down on torque Considering that it makes 21 inches of vacuum in a 6.0. Thatís the cam thatís in my turbo LS and There really is no noticeable lope over the stock cam. But in all fairness I have a bit of converter in the car.

Re: 6.0 cam recommendation

Heard that too...buddy wants to give me a low mi Ls3 cam but hear they are soggy in the truck
So ill get the proper cam.

I was told (10 yr anniversary yesterday) shes splitting in 2 weeks which will again leave me in a lurch so once again have to shelve all projects. Fn women I swear they are dream killers. Guess I have to start selling stuff again.
LAST TIME I deal with this crap.

Would a converter be money well spent or will the stock suffice? Not interested in 1/4 mi just a good sound OEM driving car just better than what it was.
