Nice keep me updated on what you like better... I would like as loud as possible under acceleration with no drone at highway speeds (and something to show off my cam)...

I dont know if you saw but do you have any vids of you exhaust now?

Not true. Always replace the pushrods with hardened units when doing a cam swap. I don't care what anyone says or doesn't say. If you're already swapping springs, pushrods are easy enough to do.

If you want to go without the pushrods, see you in a few months when you bend the stockers.

My opinion on your mods - FWIW:

Have Patrick Guerro spec a cam for you, and RETAIN THE VVT! Install good valve springs and pushrods at that time
1 3/4" or 1 7/8" ARH or Kooks LT headers
Retain the OEM cat-back. Sounds absolutely amazing - especially with LTs
A good tune - ECM and TCM

If you want to race it - a high-stall torque converter will pick that truck up a MINIMUM of .3 in the 1/4!

That'll do it!
Who is a good tuner that knows how to tune a VVT cam on an NNBS?

It was a question... more or so asking if I need too. I will get hardened pushrods as well then...

Your way safer doing the pushrods. Esp since your swapping springs. Also do some research on going with a VVT cam, a lot of people from what i have been reading wished they would of just converted to a regular cam. And theres a few specific posts on the tuning issues with the VVT cams. Just a little FYI, a little research will always pay off so take the time and do the homework.

Also when you get rid of the resinator you'll have the usual 1800-2200 rpm drone. I have true duals into aerochambers dumped before the rearend on a 07 silvy 6.0 and i have drone at that rpm, esp when it kicks into the V4 mode.

Ok... so I will probably end up keeping the resonator on it... I HATE drone...

I read a couple posts about the VVT cams and tuning but I think if I went conventional cam it would end up making my daily driver not so drivable...

what is all involved with turning my truck from VVT to conventional? parts needed, ect...?

i dont plan on racing this truck every weekend or anything like that... its more just to play on the streets with. so if i can convert to a conventional cam without packing on too much more money and still keep drivability and fuel mileage I am all for it! but keeping VVT will probably end up being cheaper and easier?

What I want is the EASIEST most RELIABLE way to get some performance out of this 6.2l... I am already going to do LTs and ORY pipe so naturally a cam would be next.

SO what should I do for the cam? keep or get rid of VVT? if get rid of it what is all involved including parts or if there is a package deal on them?

Thanks

i dont have vvt or have never owned a vehicle with vvt. but almost every cam swap thread ive read they have deleted the vvt and didnt look back. i guess it just makes it alot easier and simpler in the long run. hopefully somebody else will chime in more info?

I was just reading a parts list and from what read you need a DOD kit: LS7 lifters, GM valley cover, Head gaskets and i guess the push rods are the same lenth so thats up to you about spending the $$$ on hardened ones. But as long as your doing a cam you might as well since you will need stronger springs. And if you pick a samller style cam with good low end and not too high of a lift it will be streetable esp. with a good tune.

Anyways i forget what else is included in the kit So just do a search on D.O.D. KIT

And when you choose a cam make sure you talk to some members with similar style cams and similar uses of their trucks. And you'll be more than happy with how much your truck wakes up esp. with LT headers.
