Default 2005 LQ4 for boost?

Hey guys,

So I currently have an LQ4 ripped down to the block in my garage and am curious as to what the best brand of cam bearings would be to go with in this thing, as thats my next step.

I want to twin turbo this thing. I've been looking at twin 60mm's with .63-.81A/R exhaust turbine housings.

I'm looking to stick with the stock bore, just get a hone. Motor supposedly has 160,000KM's on it. Would that require getting +.005 pistons or?

Going to freshen up the stock heads and run them for now, lightweight valves, nice springs, rocker arms, etc.
Whats the consensus on pushrods for a boosted engine?

Looking to do forged pistons & conrods, but was just going to run the stock crank. I don't wanna go too far over 600HP until I can build the 4L80E up a bit more. (Advice there?)

Also, I'm going to have to start with a mail order tune, and then figure out where the closest reputable dyno shop is to me in Northeastern BC here...

Who would be the best guys to go to for the mail order tune?

Also, who is the go-to guys for wiring harnesses?

Motor & transmission is going into a 4-linked 1994 K1500 Z71.
Has a 9.5" 14-bolt with 3.73's that I'm going to install a tru-trac in. Will it take the power?

I have a 241C transfer case I do believe that is SUPPOSEDLY out of the same truck as the motor, and I do believe it is already floor shift. But I don't have the plate for inbetween the transfercase and the transmission, so thats a current issue. I don't plan on racing this thing in 4WD at all. Just want 4WD because I may have to winter drive it for a couple years.

Any advice here is welcome guys. Thanks in advance.

Well I was honestly going to go over there with this post, but as far as the main initial question of what a high quality cam bearing is, I thought here might not be a bad place. I'll repost it over there. Maybe a mod can delete this.

Thanks.
