What stage II would not lose much low end torque. Crower stage II seems good but how good are comp XE270s and what spring should I get?
Stage II cams?

Don't get blower cams unless your plannig on going S/C. You'll end up losing more power since they are made for having a power adder. They will sound good and pull hard but if you want your cams to be sound and performace go with the 270's
I am getting tired of constantly correcting this Bull**** theory. One of the best N/A cams out there is the Comp 270, the Crower Stg 2 PI SC cam is almost identical to it with the exception of having more lift. It too works extremely well N/A. I am using the Crower Stg 2 PI SC cam in a N/A car that will never see a SC and am having great success with it. What one company considers a blower cam, another company has a N/A cam that is similar spec'd to it and vice versa. What matters most is the cam specs...
Just to show something here, I am posting the Comp 270 specs and Crower Stg 2 PI SC specs:
Comp 270:
234/238 @ .050", 109/117 113 LSA .550" lift intake and exhaust
Crower Stg 2 PI SC
234/234 @ .050", 110/118 114 LSA .581" lift intake and exhaust

Do you have any sound clips? The only other thing I would need are springs right?

Don't mean to jack the thread, but it may help some people out sound wise.
TGJ:
Which cam will be better sound wise. The Comp 270 or Crower Stg 2 PI SC? What I will be looking for it that nice lope sound, noticeable but not extremely aggressive. I am a complete noob with cams
I have heard a few cars with 270's and it's idle is more lopey than my car. That said, my car because it is a 5.0L Big-Bore does make cams more mild, therefore less lopey. I would expect that my cams in a 4.6 would be just as lopey as the 270.
n/a cams have more of a lope than a blower cam,because of the lsa. n/a can have lsa in the range of 108 to 112 and blower cams in the 113-115 range. thats why a blower cam with the same duration and lift will have more lowend power. Even Vt say's that their stage 3 blowers make more hp than their stage 2 N/a on a n/a motor
Ill second the blower cam opinion. Ive seen quite a few cars perform well at the track with the blower cams and a low gear, NA. Also, DYNO Queens dont always equate to the fastest track car. There is more to a cam than just peek HP.
Always look at the specs of a cam, not the "stage", and ask different manufacturers what they recommend. I wouldnt go with a custom grind on a stock head, stock compression motor unless there is no extra charge and you are confident with the grind. I used the old erson reground cams, the lope was nasty at an idle, but the specs turned out to be wrong. Long story short, get with somebody you trust to set and degree the cams properly if you are not doing the install.

I do want to get a blower someday soon (year or so). So then it would probably be best if I went with blower cams. I will talk with Tim at MPH and see what he says.

on the same note tho, N/A cams seems to perform well on FI cars like hotmustang's

You should look at the specs on each cam. They are both "stage 2" but Crower's have more lift ( I think .559 intake and .570 exhaust) and less duration. Comp 270s have more duration but both .550 gross lift on the intake and exhaust. More duration makes a choppier idle, but my Crowers have a unique sound. Crowers have less duration to prevent PTV contact. You can't have too much of lift and duration or it will cause PTV contact
