0cc. The primary difference between LY6 and LQ9 is their compression ratio, with the latter having a higher value. While a higher compression ratio translates to a higher output, we see that LY6 is more potent than LQ9, though by a slight margin. The other contrast point between the two engines is their piston style.The only differences were: The LQ4 came with dished pistons. The LQ9 came with flat top pistons. (This raised the compression ratio, horsepower, and torque.) The LQ9 had injectors with a slightly higher flow rating. If you don't have the VIN code, you will need to inspect the pistons. This means removing the cylinder heads or using a Borescope.The LQ9 is the higher compression 6.0 (10.0:1) out of a SS Silverado,escalade,VortecMax truck The LQ4 is the lower compression 6.0 (9.0:1 I believe) The 5.3 came in trucks,suburbans, and tahoes.
