Just look at some people on this thread, and others. Its been proven, you really dont need huge cams in order to go fast.
Now if you want a big cam, thats different. I just dont believe that in most cases, a big cam, will offer any huge performance gains, to make it worth what you can lose at the lower end of the scale, especially when off boost.
Dont get me wrong, Im not saying Stenod or Cam-Motion are wrong. They have a lot more experience than I do, Im just offering my opinion, on what I know from my own experiences and limited knowledge.
But for Cam-Motion, they reccomended me a 23x/24x cam with circa 0.600 lift on 114 when I requested a cam for easy 10's and 140+ traps for my car...
I knew that cam was far far too big for me, so I opted for a 224/230 on 115.... Im glad I did.
It depends what you want. I want a car that idles smoothly, and performs superbly...almost from idle, thru to 6500-7000rpm.
A big cam will never do that. IMO, big cams arent necessary on a turbocharged build ( and to a lesser degree blower build ), unless you need or want to use in excess of 7000rpm.

Another difference with me is I did not want a perfect idling and driving cam. I am willing to sacrifice some bottom end and idle smoothness for a top end screamer. Who races at 2500rpms anyway? I will be stalling to 3--4k off the line anyway.

You see, due to the shape of the efficiency islands on turbochargers, you actually have a higher ultimate power potential with a smaller cam running more boost than you can with a bigger cam and lower boost.

If I was an auto, on better tyres, low 9's would be a doddle.
My car will never be an auto though, its not what I want. It would just be too horrible and thirsty for normal driving, and have no top end. My 60's are still in the mid 1.7x range. I'd like to see that in the 1.5x, which would have a massive effect on my ET's
I also figure if Im abusive enough and really nail the launch, and maybe powershift too, I can run mid-high 9's without too much difficulty, and still do the 800 mile round trip to the track and back.
What more could you ask for a full 4 seater 4 door road car that runs pump fuel, albeit with a little meth
....that idles nicely lolOn a cool day, I dont think the meth even makes much difference.

You guys make feel bad about my TU1 cam (225/225 .581.581 113). Oh well, I am gonna see what it will do witht he TC76MPS and then a PT88.

I'll be in the 8s soon enough with a 222/228 .550 lift cam 
And I'm still running single valvesprings, original stock pushrods and the original 98 lifters this car came with @ 7000rpm with zero issues.
It may not drop any panties when it idles but it does OK
