LS1/LS6 vs LS2/LS7?
Basically the LS1/6 are 346 (3.899" bore x 3.622" stroke), the LS2 is the same as the LQ4/9 6.0L 364 (4.000" bore x 3.622" stroke) from the truck, except with an aluminum block. The LS7 is based of off the 427 C5R 7.0L (can't recall bore and stroke) and shares very little with the LS1/6 and LS2. The LS2 and LS1/6 can share many components.
This is a very basic run down of the differences.

Wasn't there someone on here that looked at LS2 and LS7 stripped blocks and said they had very few differences?

So basically, the "Gen IV" designation is really not completely accurate then? Because the Gen II (LT1) was very different from the Gen I, and the Gen III (LS1) was a complete redesign from the Gen II. If the LS1/6 and LS2 share a lot of the same parts, why does GM consider it a completely new generation of engine design?
