I am planning the following mods and need to know what's the best dia. headers to get.

- Lingenfelter CAI:

- Lingenfelter cam + spring kit:

- Kooks LT's with catted mids

Does this cam justify a 1-7/8" dia rather than a standard 1-3/4" dia tube for the Kooks headers? I have a feeling there wouldn't be enough back pressure but wanted to be sure first. I have about $2,000 to spend and want to make this upgrade count. Does it sound like a good setup for this amount of money? Feel free to suggest alternatives.

Thanks!

I have that cam. I think it's a little too small for an LS2 though. Its only a little hotter than what you have now. 1 7/8" is over kill for that cam.

Any cam you get will need a tune to go along with it so factor that into the price as well.

You know of anything a little more aggressive that won't sacrifice a reasonably smoothe idle? This is my daily driver and I don't want to kill my engine over time. I know it's all about a balance but from what I'm reading I could still afford to increase the lift/duration a tad while maintaining a somewhat normal idle.

I'm assuming also as a general rule when you replace a cam you also replace:
Springs
Push Rods
Timing cover/oil pump gaskets
front seal
crank bolt
oil/filter ?

I have the same LPE GT2-3 cam and the Kook's 1 7/8 headers. You don't need to worry about the 1 7/8 being "too big" - they would do fine on a stock LS1, and even better with the cam/heads. The idle at 800 rpm is not rough at all, barely lopey.

The kit you linked to has the springs included, but yes you want to replace those.
Push rods are not necessary, depending on the heads you use.
Timing cover/pump gasket - optional
Front seal - optional
Crank bolt - buy the longer one.
wouldn't hurt to replace the oil either.

EDIT - I'm basing this info on an LS1, just noticed you're an LS2 - as others have said, I wouldn't waste the money/time on this cam with an LS2.
