6.6 L92 cam?
How on Earth could anyone make other that a wildass guess for cam specs without knowing all of the parameters of the engine and vehicle? At the very least, port flow at all lifts, intake manifold configuraton, rpm range to be used, transmission, gearing, vehicle weight, and fuel to be used. At least that's what my cam guy wants to know.
Anything else is merely an RE (Rectal Extraction). There are a number of RE cams floating around under various names.

Because unlike you (Thread trolling cam god) We go with the so called off the shelf cams because they have been more or so tested by others with similiar mods. I had Cam Motion grind me a cam off my specs and by far was the worst cam out of the 5 so no I do not feel what you just said is always true. Cam Motion has been around along time and they got it wrong on my build. Explain that. They gave me the exact oppostite of what I asked for. For what he is looking for I firmly believe the G5X3 is his best choice. And I bet you whatever cam specs you come up with will be real close to having the same valve events as the X3. For the street the X3 on a 112 + 4 is a great choice with his comp ratio.
You are always willing to show your *** on this site but I never see you help out anyone. I have yet to see you do anything but talk.

Now I believe that folks like Erik, Rick, Ed, Patrick, and other sponsors are willing to do what it takes to get things right.... but the Tech help from the cam manufacturers is weaksauce.
well i know futral uses cam motion and i have seen a 427 on his dyno with L92's and a cam motion cam dyno 540-550. i personally have a cam motion in my 408 with l92's and the car weighs 3520-3550 depending on how much fuel i have in it. 1.43 10.60's 126 and some change. this is a street car. drives well and the cam is 232@.050. also wize did you get any #'s yet?
Let's make one thing clear, I am not bashing Cam Motion at all just trying to get my point across. And the last 2 cam specs posted are real close to X3 specs, just different valve events.

To do this scientifically, even for an engine where you know all the flow, intake, etc. parameters could involve looking at hundreds or thousands of possible cam combinations. Yes, it helps if you have some approximate idea of where to start and how to do it.
So, if someone is spending good money for a cam for a 12:1 408 built for max hp, like the OP in this thread, I dare say the shelf cams out there are not optimized for that configuration. Folks who recommend a shelf cam or something that may have worked in their buddies' engine, but change the rocker ratio or ICL, or whatever are just spreading bad advice, even if they don't know it. That's not as helpful as suggesting a custom cam, IMO.
I would rather see people get real value for their cam dollars. If they choose the right source, they might not have to buy and test 5 cams. They might even have better results than the try-5 approach. Have I seen this happen? You damn betcha! Do I think there is a better way? You damn betcha, and it's cheaper that the try-5 or even try-2 method. Value recieved for value given. What a concept!

For a N/A motor setup, I would run a 108-110 lobe separation, duration depends how high you want to rev it, I would imagine you would at least go 240-250@ .050 with at least .600 lift.
If you plan to spray it or FI, I would run a 112-115 Lobe.

Verdad Gallardo These heads do not like anything more than 112. 111 gets to be very close to the edge and the 110 are horrible. Again valve events will determine the lsa.
I don't do cams, but I do have a fair knowledge of how engines work, so my advice is to leave the cam specifiying to someone who understands engines, and goes about choosing valve events the engine/vehicle/driver package wants. Read that as "custom cam" and not an RE "custom".

Are not "valve events" pretty much what cam specs are all about?

I agree with everything you said. However it seems that there really isn't any L92 cam stuff that is public on this site at this time. Everything has to be top secret because of other vendors copying. The try 5 method only cost me time. And since I do my own work it was not that big of a deal for the knowledge I gained but I know most could not have done this for as little cost I did. That is why I am trying to give my opinion on what I have seen with a similiar build with that high of comp with these heads. I have tried the custom cam stuff and the non LSX group like Comp or Crane and others seem to have very limited experience with the L92 stuff. For any kind of street driving with this car I really feel he would be happy with that cam. Is it the most perfect cam I do not know but I do not feel it is pretty close to it. I would like to see what an L92 cam guy would recommend and then I would like to compare the valve events of the X3 against it as a reference and I feel for an off the shelf cam this is a great choice.
well after reading all of that I will have to say that its all good info just a little heated. I am going for max HP but I would like to drive this car more than just the strip. now if 1.8 are too extreme then I wont use them. but if I need to get a different cam to make more power i will. I'm just reading and learning at this point and if i need a custom cam then thats what I'll get. I just want to get everyones input on what they think will make the most HP
If you want max hp. get TSp's 257/266 on a 110. It will run extremely hard up top but on the street you will regret it. I was in your situation last year. I wanted max hp, well there are alot of sacrafices for street driving with a max hp cam with these heads. And my car is a garage queen with 23,000 miles on it and it was too much of a hassle to drive on the street.

When you get serious about this engine build, go to one. Yeah that's blunt and not what you wanted to hear, I'm fairly sure, but that's what the folks who really run well do.

Because if he wants to drive it at all on the street it will not work too well. Besides if it was an all out hp build he would have went with better heads imo. Not L92. Good cheap performance heads. No where near a max effort set of heads. But I am done posting my opinion on this thread. I gave my opinion and really do not care what he does. He asked a question and I tried to give my OPINION on what I have experienced in the last 2 months. Good luck and have fun.
