I just wanted to clarify a few things in this thread. First the LSX is a code the aftermarket has used to describe the GM Gen III and Gen IV small bock V8 engines. This code or term is not completely correct because not all Gen III and Gen IV engine use a LS for the first part of the RPO code. The reason I brining this up is because GM has just released the REAL “LSX” block and it will be out in March of 07. This new block called the “LSX block” will be a cast iron street/race block that came withstand up to 2500 Horse power and live. This block can be purchased for around $2000. It can also be bored and stroked to over 500 CI. GM will also release a cylinder head to go along with this block in the very near future.
To address another question about why someone would remove a LS1 and install a 6.0 L from an Escalade, LQ9 engine. Because an LS1 is an aluminum block and the LQ9 is a cast iron block, much stronger. The LS1 is only 5.7 L and the LQ9 is a 6.0 L. The stroke is the same but the bore is bigger on the LQ9, 4.000 bore on the LQ9.
To clarify the information about the new L92 engine in the escalade. This engine is used only in the 07 Escalade or 07 GMC Denali. It is a little different that the LQ9 engine GM used in the pass Escalades and Denali. The L92 is a 6.2 L aluminum block and new cylinders head that will bolt on any Gen III or Gen IV small block. The heads on this engine are unreal for the price. These heads to flow 330 CFM on the intake side and you can buy them complete for less than $400 each. What head can you buy for any engine that will flow 330 CFM for $400?
As to expense to build one of these engines. May people, and I will be in this group in the near future, have produced over 1000 HP with a stock cast iron 6.0 block, stock cast crank and stock cylinder heads with a turbo. These engine need CNC work on the head, rods, pistons and a camshaft change to get to this level.
If you wanted to do a little research take a look at the past issues of Popular Hotrodding. I think that ran this article about 14 months ago on a turbo Gen III small block. They used a stock cast iron block, 4.0 stroke crank, dart heads, camshaft change and a t88/98 turbo. This engine made over 1100 hp at less than 15 pounds of boost. : )
The Gen III small block is the hot rod engine of the future. I believe this engine will take over the Drag Race seen in the future.
Sorry for the long post.
