Ok this is what I have:

2003 5.3L z71 Avalanche 4.10
Mods:
Corsa Exhaust
JBA Cat4Ward Headers
Intake
Taylor Wires
SLP Rocker Arm Full Package
160 Stat

Mods going in a week:
Flex 282 Fans
200 Amp Alternator
Eaton Posi
BP Tranny
2600 Stall TQ Converter

Anything else should I do to the engine before putting in the Radix? Heads, Bolts, Forged Pistons?

Any feedback would help alot.

Right Now:
283 RWHP...Tuned by SLP.

 

Dude you are already way ahead of the game! That will make a nice running Blower motor! you will be very satisfied with a Radix!

 

You do not think I need to do any headwork, pistons? etc?

Thanx for responding.

 

I am running a 50k+ stock bottom end with no problems......SO far

 

The radix is designed for a stock motor. That is why it comes with injectors, tuning, intercooler, and everything else.

 

Thats pretty damn cool!

I know that a silverado weighs alot less then an AV....my truck weighs 5750...about 6000LBS with me in it. What you think I am going to need to get the rwhp & rwtq to get this beast in the mid to low 13's 1/4 mile?

by the way here is the link to my truck:

Correct, this kit is made to bolt on in one weekend and go run with the Big Dogs!

 

I guess no one has an estimated guess on how you get 6000LBS to low to mid 13's in 1/4 mile meaning how much rwhp & rwtq.

Thanx. =)

 

The H2 we put the radix on last week runs incredible. I will be taking it to the track in the near future an that will answer that question for you!

I est the Crank hp in the 500 plus range.
