Default 06 TBSs LS2 to LS3 heads

Hello, and happy new year to all.

I am looking into swaping the heads, and camshaft on my 06 TBSS AWD.
(I have done lots searchs on many dif forums. Not having the greatest luck so far.)

I am looking into doing LS3 heads, and LS3 camshaft.

First hump is theintake.
I know req's LS3/L92/L99 style intake.
I want to keep a truck runner size for TQ.
Does anyone know truck intake that works??? Year, engine vin # ( 8th diget ).

Will the OE throtle body fit new intake?
IF not what year throtle body was used, and does it plug in OE connector? Year , engine vin #

That seems to be bigest problems I can think of currently.

Also like put set shorty headers on at same time.

Will be doing this when I go into engine to replace the pistons/rings.
Mine has lite piston slap at cold start, and gm has updated pistons for oil consumption.

The book says LS3 ( part # 12615879 ) has 70cc chamber.
It has been replaced by part #12629063 and has 68 ccchamber.
Spec on my LS2 belive 64.5cc chamber.


Thanks for all help.

Default L92 info

The intake you need L92 Truck manifold is 12580678 it is the same intake for the 6.0 LY6 and 6.2 l92.The throttle body Is a four bolt style witch is what you should have on you TBSS and it is the same 90mm size so you should just bolt yours right up.The heads are not really different even know they have different p/n'.If you want to know what cc the combustion chamber is any good machine shop can check for cheap.They only thing I see that might hold you back is the shorty headers.The LS3 heads flow good from the factory on the intake side but the exhaust port is a little restrictive so you want a good header to move some air.
