But there are some questions still without an answer so I hope someone will bring their opinions for that kind of stuff I wanna build.

So I have to figure out what kind of pushrods should I use and a throttle body - should I have to port it maybe?
My engine is '04MY so it already has a DBW TB, also I have a cable TB from the LS6 intake (both are 3-bolt pattern) AND I also can get a 92mm FAST TB from my friend but it has a 4-bolt pattern and came off LS3 intake.
Googled an adapter and founded some (to assemble 3-bolt manifold with 4-bolt TB) but does it even work?

And I forgot to mention that I have 2 hasness kits - first one came off the Tahoe for the DBW (along with the engine itself).
This is not the best option for me because I would like to put my ECM behind the dashboard but not inside the engine bay.
And the second one came off '02 Camaro but Camaro had a DBC setup.
Althrogh I have only 1 PCM from '04 Tahoe (and I hope it can work with DBC, I'll theck it today).
Drive by cable setup is prefered because it's much easier to install just 1 particular cable instead of electronic pedal, black box and harness for all that BS. I have all that but would like to keep things simple.

Truck intake can not be used anyway because of hood clearance. Unfortunally.
There're pushrods and 3-to-4 bolt TB adapter plate left to figure out...
Cam specs are:
Lift: 0.585"/0.585"
Duration @ 0.050": 228°/230°
Advertised Duration: 283°/286°
Lobe Separation: 112°

Yeah but if only my PCM can run DBC setup...

Still no entries for a pushrods?
Ported and polished my DBW TB from LM7:
Assembled it with LS6 intake manifold, will be using motor's OE PCM and harness, I guess it needs to be rewired but thanks to lt1swap.com - found all the schematics.

Run the stock (7.4) pushrods thats what the sloppy cam is intended for. I recently did a identical build. The only difference is the intake (LS2). The engine n/a makes somewhere in the 330 rwhp range.
