Anyone using cam motion Titan 3?

Brett @ Landspeed who ported and milled my heads said he has customers pushing 40k, but that set up was with Johnson lifters, larger diameter p- rods and lighter Ferrera valves.....For the money that would cost, I would rather just change the Valve springs.

Here’s the Titan specs
Duration - 227/237
Lift - .621/.604
Lobe separation - 113
Intake center line - 109.5

This cam will do fine.

I have a Lingenfelter GT1-1 cam in my daily driven Impala.....
229*/242* with a 114* + 0* LSA

If I had it over to do again, I'd have gone with a custom grind VERY similar to the BTR Stage 3 cam....
229*/244* with a 113* + 3* LSA

Best of luck!!

This would be true with Texas speed though their stage 2 or 3 is definitely in the running.
Just don’t want to be kicking myself after the job is done

Yeah all their LS3 cams have the same large lift, just different duration for each stage.

I have a new in box Tick Perf. Stg 2 street heat cam for sale in the member classifieds $300 shipped.
229/244 | .618”/.610” | LSA112+4

Cam motion seems to be where it is at. A lot of cam companies have their cams either supplied or send off specs to cam motion and then they make them for all these speed shops.

That’s what I was thinking too. I understand the draw to the other companies though with their easy to build cam packages
So many options!

[ss camaro-monte]

Yes, every other cammed Camaro I see is a GPI or TSP followed by Tick or Brian Tooley. All are good cams but I want to say Tick and Tooley use Cam Motion cores but don't quote me on that. All good cams though. I have heard a Titan 3 in person and it has some definite chop to it.

My cam is 243/255-.649/.629-111 and run PRC 260 heads. I daily my car with a th400 and 4.10s with a 6000 stall. 3500rpm on the interstate is roughly half my driving.

My GPI SS1 cam is an 8620 core ground by CamMotion. I ordered the package through GPI, they sent the cam order to CM, and then CamMotion shipped me the cam itself while GPI sent all the other parts of the package. I received everything within a day or 2 of each other.

I don't know if all GPI's cams are ground by CamMotion or just the 8620 cores, but either way it was an easy process. I figured for only an extra $50 the upgraded core was worth it for piece of mind. I don't think they will grind a VVT core on 8620, but I'm not sure why. All that said, if I was getting a truly custom grind I would probably just pay PatG to spec the cam and then have CamMotion grind it.

As for changing springs at 20-25k...I figure with the few miles I drive it's a small price to pay to not have to worry about a major failure, so I am not too worried about when the time comes.

The Titan does sound good on the videos. Did the car you heard have a low idle?

[ss camaro-monte]

No, I wouldn't call it a low idle at all. If you mean the thick chop where it definitely seems like the car lopes so much the car might stall. I have seen a lot choppier or loopier cams then the Titan 3 in a ls3. A lot of that is in the tuning of course but the Titan 3 is on a 113 lobe separation. The 110-112 seem to have more chop to them for sure.Not drastically but if you have two cams with similar duration the higher lobe separation will tame it some. I have seen several of the GPI SS2 in person and I think they chop harder than the titan 3 but they are 112 lobe separation slightly higher duration and more lift.

I always thought the BTR stage 2 sounded really good for a stage 2 cam.

[Agent WD-40]

I ran a Livernois stage 2c (regular lift version) for ~70k miles without changing the springs. Had a rocker issue and replaced springs at that point. I daily drove the vehicle too. Loved the cam, worked well with my auto trans L99, and had a nice chop. Knowing what I know now would have probably done springs a bit sooner though.

That said, I would probably pick a low lift LS3 cam in the future (even in a weekend toy). I like the idea of being able to run factor springs and other parts and not worry about maintaining springs, rockers, etc. Will still get the sound I want and make enough power.

There are TONS of choices for cams that have .55x lift that will make plenty of power and sound good. Cam Motion makes a series of “Mild Performance” LS cams that come in low lift versions (see stage 3 below).

BTR, Texas Speed, and Cam Motion all make “truck” cams that are in the .55x lift range like stock LS3 and are designed to be dropped in with factory parts. This reduces costs and should keep you close to factory reliability. They haves ones will idle like stock or be more aggressive on sound/power.

2c Cam Spec's are:
Intake Lift 224@.050
Exhaust Duration 236@.050
Intake Lift .620"
Exhaust Lift .620"
LSA 117

Cam Motion LS3 Stage 3 Camshaft (220/230-117+4) would probably be similar to 2c cam but lower lift.

There are a ton of other truck cams too if you look.

Thanks for the input but For several reasons I think I’ve decided on Texas speed stage 3 kit
- TSP Stage 3 N/A LS3 231/246, .640/.615, 111 LSA Camshaft

It seems this cam makes good power, sounds good, and isn’t max lift or duration
