Please help with explaining these cam motion characteristics

[rich2342]

Do any folks here have Cam Motion cams?

I spoke with an installer who works with Cam Motion.

He recommended this one which I am curious about. In addition he mentioned the Titan 2 and Titan 3 cams.

1. What are the differences in these two cams?

2. Which would make more power under the curve?

3. Which better driveability considering M6 with 3.91's?

LS3 Stage 3 Camshaft (220/230-117+4)

Titan 2 LS3 Camshaft (222/230-113+3)

Anyone have this cam or experience/exhaust idle clips?

Those are both very mild cams (compared to other LS cam grinds) and should offer good driveability when properly tuned.

The stage 3 has a square lift profile of either .553 or .595 lift @ -9º of overlap.

The Titan 2 has a lift of .595/.587 @ 0º overlap.

This is a perfect example of how you shouldn't compare stages between manufacturers as my little Stage 1 GPI LS3 cam has a lift of .647/.638, 224/237 duration/112 +4 @ 7º of overlap.

Exactly

The term “stage” shouldn’t ever be considered a descriptor

Which would have a quieter idle? I was previously looking at even milder options fearing state inspections. LPE GT11, Livernois 1c, Little Lunati.

Local installer deals with Cam motion and after informing him I want good power under the curve low, mid etc. He suggested these which look almost similar and the Titan 3 also.

So, Titan 2, Titan 3 and stage 3 ls3 cam.

Looking for best balance of power and driveability and quiet idle.

The tighter the LSA the more bottom and midrange torque the cam can produce.
The tighter the LSA the more lope the cam can produce.

Whats considered tight Bo??

I have 228/242
LSA 113+4
Lift 627/605-8

[Bo White]

106 is tight
Realistically though in the scheme of things for traditional LS cams anything below 112* is considered tight. Imo that's the point where it starts to get fun ��

[rich2342]

I am bucking convention with my options.

I am leaning toward the Titan 2. It has 113 3* lsa.

What might I gain with this cam seeing I already have lth, gears and intake?

I am looking for stealth idle and broad power from low rpm to high.

The intaller also recomends the titan 2, but high lift version. These are the lifts published 595"/.587. Not sure the high lift spec.

Would this cam work for my goal?

Ok one thing I want to add is about lsa on a cam.Its lobe separation angle. It should be considered but you must use the duration with this to really know what the cam will do.
You can have two cams one with a 112 lsa and short duration With say 4 degrees overlap and one with a bigger lsa and longer duration and it might overlap 15 degrees.
Which one in this case will idle better.
Usually the one with less overlap.

So all the specs need to be considered as a whole.

I guess it will depend on the high lift spec. Infidel, above figured 0* Overlap with intake/duration and lift listed. Not sure high lift spec.

Their LS3 stage 3 is 7* Overlap, so likely the Titan 2? What effect will higher lift have assuming other specs are the same?

Not saying that the cam isn’t correct for the engine and likes.
Just using an example of how bigger lsa might not give you what you are looking for in a cam.
My number were way conservative.
You just can’t say that a cam with a bigger lsa will idle better.
It depends upon a lot more then that.
Unless of course the cam is exactly the same except for lsa.

Now higher lift will usually give you more flow if the heads are good enough.One reason is the valve when higher has a bigger opening for airflow.Another is that most higher lift cams have the valve open longer at different lift numbers. this is of course an over simplification because cam profile affects this also.

Point is more goes into cam selection then just one or two things.

My advice is to get multiple cam recommendations call up multiple cam manufacturers and see what they say if most are at a certain duration,lift and lsa then that would probibly be the correct numbers for what you want to do.
Then just pick the brand that you or your mechanics likes with those specs and you should be good to go.

Why not talk with Kip at Cam Motion? Great guy to talk about cams and your goals, sort out your goals first.

[rich2342]

I am going with the below setup.


- STAGE 3 CAM 220/230 117 lsa +4
- dual valve springs
- hardened pushrods
-melling standard pressure oil pump
-CHE trunnion kit #4290

[Bo White]

Titan cam will make more power.
