Why not a custom spec'd cam? They do take a while to get but are well worth it in the end.

The reason why I am not going with a custom as of right now b/c I PROMISE I am going F/I. I am just not sure b/c the options are endless. As of right now I just want this all in the truck and running b/c I miss my Hoe!

Once I everything is up and running right for a decent time and I finally pick a F/I route I will re-do it with a custom cam.

I do see in my future either a turbo or procharger with FAST truck intake...that thing looks bitchin (truck intake vs car).

Here are some pics...sorry for the mis match in pics but I am too tired to put them in order. Valve covers are going to be all Black. I was going to leave the lines in the Valve Covers Gold and rest black. Well When I removed the tape...the tape removed the gold paint...so now its all Black.

















Found a Complete L92 Intake, ordered the parts for the LS9 Cam Swap and Lifters

Next is L92 Rockers and Guide plates
Push Rods
Crank Pulley (Don't ask) if you have one laying around I will buy!

The 6.8-7.8 should be good. Here is a link.

By the way, I like the color choice. Different.

heads setup:
The heads are a stock CNC'd LS3 head, they have not been milled or decked. The chambers are stock cc size, 70cc. If you're using the LS7 lifters, then the 7.4 pushrods will work.
PRC LS3 and L92 CNC Ported Heads


Rocker setup:
12569167 - intake rocker - 8 needed (L92 or LS3)
10214664 - Exhaust rocker - 8 needed (ls1, LS2, 4.8, 5.3, 5.7, 6.0)
12600936 - L92 rocker stands 2 needed

This is the trunion upgrade, or bearing upgrade. Since you're not running a huge cam with a big duration . . . it's not needed.
COMP Cams LS Heavy Duty Rocker Arm Bearing Assemblies - Set of 16 - Lingenfelter Performance

If you want to run the LS9 cam:
Get the LS2 timing cover,
LS2 cam gear,
LS2 cam sensor

The LS9 cam is a 3-bolt cam, but there's no cam reluctor in the rear. So get the above parts for your GEN III motor.

THANKS!

I ordered all the LS9 Cam stuff two weeks ago from GMPartsdirect.com. I still have not received it yet due to the fact they are waiting on a bolt to complete the kit. It is unlike them to take this long usually arrives with in the week.

Would upgraded Rockers work for my app? Only extra $100
Yella Terra 6667 - 1.7 OFFSET NON ADJ ULTRALIGHT ROCKER SET FOR L92/LS3/LSA/LS9/L99 | SDParts - 1-800-456-0211

(Just want to repeat )My App: B/w 500-600HP with boost. From the research I am doing...I will be b/w 400-450hp N/A.

My Boost will push me a little over 700. I am not looing to drag race this thing...just some fun here and there. Might look into a Ralley Race (just one) for poops and giggles.

Thanks,

I went with gold...this motor is worth $$$. If I ever have an oil leak I will be sure to find it!

I am painting the transmission purple. Don't ask me why but I was torn b/w the two colors for the block...gold or purple and I chose gold!
