So just to interject meaningless drivel, I'm always with tech when it comes to making changes to a giant pig of a vehicle in the name of speed....seems pointless. .....however
Met a lad 2 weeks ago and spent some time with his 06 Denali....again, 5500#+ truck..... drives it daily, runs mid 10's
Open hood, 572, canfield heads, 1000cfm Domimator. Huge Solid roller, TH400, custom 4000 stall, gv od, 9" rear.
Truck looks stone stock, and whoever tuned the Carb and timing is a genius, drives really nice and a claimed 10mpg
Again, looks stone stock, and I know my 06 avalanche with a 5.3, a tune and a cat back exhaust with 35" tires never got better then 10-12mpg
It only takes money lol.
That my pointless contribution.

SOme of these GMT 400 trucks, are now being out weighed by new "Sport Cars". My truck is about 400 lbs lighter than a Hellcat Challenger.

just an observation.

Hey Calderone, can you take some pics of your heads for us? Thanks.

This is teh tunnel ram intake manifold that your setup needs.

90mm throttle body, this intake would suit your heads perfectly.

Thanks Hogg !
First of all, the intake alone looks like a lot of $$$$
$1,365.21 for the manifold only, plus we have to get the rest.
Maybe down the road but not sure if it's worth it since it's no
race car but, might help a lot with the power.

We don't have the 0912 heads yet but we are sold to AFR
Here some pictures of the L98 heads i used to upgrade my 87 Vette
and they are a piece of art, so that's why we chose to use AFR again
for the Yukon.

Comparison with the stock 128 Alum head:

Thanks for those, but whenever you get the AFR Vortecs heads and you remember.

I wouldnt even consider buying any marine intake stuff new. I did my complete crossram for CA$1000 including tuning. Just the parts would have cost US$4000 if I bought new.

Even this dual plane Vortec marine intake would be better than stock. I'm told you can find them for $300 complete.



Thanks man.

$ 1000 is a great price for a complete set up !
Paid $ 1500 for the complete Super Ram years ago (for the vette)
I would have loved to use a Super Ram or TPI for this Yukon
but too much involved with the computer etc.

Please let me know more about that $ 300 complete Vortec intake
that is a steal ! Looks like the Edelbrock aftermarket units.
or maybe im wrong but those goes for $ 4000 (complete system new)

I know the intake is the limitin factor here, i was surprised to learn
that no company has offered some kind of upgrade for our trucks.

The $300 would be used off of ebay or something.

It is mentioned here. its a cool little forum all about our trucks. I'm Pauly over there.
"Carb" style manifold W/ MPFI discussion

I paid around $600 for my crossram intake, it came with teh marine 25 lb injectors, a few dollars for fuel attachments. The install kit even came with GM colour coded injector wiring, the guy even drilled the water pump bypass for us.
Even with the stock tune (injector flow rate changed of course) I noticed a seat of the pants gain in off idle low rpm torque and upper rpm power, on a bone stock Vortec 350.
This was backed up by FAST355 when he did some dyno testing aftyer his conversion.

I'm sure you got some gains,but,FWIW,I would take any of Fast355's dyno claims with a grain of salt & slight skepticism.Not to take anything away from him.He does have some knowledge on tuning'etc'but'his #'s are often extremely,well,unbelievable for lack of a better word.His build can always make 40 to 50 HP over someone else with the same setup. Like the 355 with a 210* cam making 380 rwhp in an Express van thru a 14 bolt GM corporate rear end.He would need to be making over 450 HP @ the flywheel for those #'s.

The Ramjet is a really good option for you.The entire kits are pricey,but,you can buy a new Ramjet intake for a lil over $500.The rest can be pieced together fairly cheaply.You can put 1 together for $1000 to$1200.Cheaper if you shop wisely.You already have the PCM,crank signal,etc. That will give you 1000 cfm fuel system that you can swap injectors to suit your needs to & IMO,it just looks cool as heck.

Yes.That's the one.It's about $2300 thru GM w/ a MEFI4 controller,which you do not want.You really only need the intake,fuel rails,injectors,regulator.Most everything else you will need is already available on your vehicle.You can do the same thing using an Edelbrock ProFlo XT as well.

I hear you. Yes his numbers are, shall we say "optimistic". Even so, his before and after dyno sheets, are both "optimistic" therefore gains shown while elevated, occur in similar fashion to my "butt-dyno". the marine intake showed low rpm torque increases, a slight decrease in mid rpm, with upper rpm power increases through 6000rpm.


I only wish I had been able to make some full passes with my complete setup in my rcsb. I was forced to let off/brake at 3/4 track due to some bad driveline vibration. But comparing the rest of my slip, I was on the way to a lower/mid 14 second pass.
