Nic or XP?

So im ordering i cam this week and im looking for some opinions. I am ordering these parts new because i dont believe in ordering any valvetrain parts used, i just dont want to take that risk. What cam should i do? I am going with 140# springs, titanium retainers, double roller. Now i know people are going to say i dont need double roller or 140 springs but im not looking to cheap out. This is my dd and i dont want problems down the road. So what i am looking for opinions on are Nic or Xp? Should i bother with lifter? oe-r or Ls7 if i do? rods? 42.5# lucas or will ev1 42# be fine?
Thanks for your opinions. Cant wait :D

I heard much better gains from nic but i imagine you dont want to tune it :P or is there something else im unaware of and honestly idk if ima end up intercooling it anyway. Next thing after cam will be building a trans so i have one when this one blows up down the road. Then once i have the built trans throwing an intercooler on is pointless ill just go turbo at that point. So i want the most gains out of this but at the same time be safe. With the nic being so agressive and needed a really solid tune would it me more problimatic to run seeing i dd it in the winter? Also wont the 60# be way overkill until i plan on turbo? im not going to be running e85 just 93 and race gas on track days.

There isn't an opinion to give, the XP cam is better both intercooled and non intercooled. It makes more power, idles better, and will get better MPG.
To read into the name of the cam means you're just falling for the marketing gimmick and aren't looking at the design itself.

The NIC isn't aggressive, it's just on a tighter LSA and lopes a bit more at idle. It is not any more or less difficult to tune, and it's name doesn't mean it makes power similar to other cams that also have an intercooler.
The XP cam is the better cam.

I made 291whp SAE (299 STD) on a dynojet with a 3.2 pulley, headers, and an XP cam non intercooled... on 93 octane.
That same setup ran a 12.7 @ 108 on street tires.

The 60s are so much better than the 42s. Not overkill at all.

Thankyou sir well then im gonna hope for 300whp with the genv and a 12.5 just so i can beat you :P

Also when do you prefer to tune this thing? I can have the cam in w/e but would you rather wait till summer or does it not matter. Im impatient so a cam sitting in my house for a few months is going to kill me :P
 
An XP cam will make more power then the NIC cam. BUT you can still IC with the NIC cam and make good numbers also.

^this is what I was looking for instead of a a bunch of no's...I have seen people with NIC cam put down good numbers also but people that go xp generally go IC at some point most people with NIC don't IC and like the harsh idle and don't care about mpg...im not disagreeing that the xp puts down better numbers just was saying if he wants to IC at some point XP would be better

Do you think i should go 125# springs or should i go with the 140#s, same price but would the 140# be more on the cam and chain for no reason? Also the fact that im using stock lifters i imagine the higher spring to more load on those aswell. I feel like if the came is good on the 125s then they would be a better bet for less wear.

I'd run the 140s all day if I had the choice.
They're both rated to .600 lift and the 140s are nitrided which means they'll last longer.
And when they do lose seat pressure you're already 15lbs ahead.
They'll control the valves much better and you'll be good to wind out the motor above 6k.

Titanium valve springs are a good idea too. They'll save a few grams I'm sure. Look into having them cryo treated to prevent wear.
 
Don't bother getting 42.5 you'll need 60# to make sure you have the flow needed for your mods. I'm thinking i'll be out of injector on my ic setup

Perfect, makes sense. I might go the extra route when i install the cam to take the heads off and check my seats, clean up the valves and **** anyway, plus it will be easier to use a clamp style spring compressor to change over the springs anyway and i wont need a compressor to hold the valves up. I dont imagine ill have any issues after i put the heads back on. Are the stock gaskets metal or will i need new gaskets for them?
