From what I can tell on the web sites, the 405 hp LS6 engine is only available in the 2002 Corvette ZO6. It is an extensively modified LS1 with new heads, cam, FI parts, etc. The non ZO6 Corvette has a 350hp LS1, and the SS Camaro has a 325hp LS1. The 2002 ZL1 Camaro web site claims it has a 400 hp LS6. They do not say if it is an engine transplant or if they upgrade the original LS1 engine to LS6 spec. The 2002 ZO6 is a quick car running mid 12s off the showroom floor. With a few modifications there are ZO6 owners running 11s with daily driven street cars. This Gen III motor was designed for serious hp potential. There are rumors about Chevy making a LS7 version with 420hp. The C5-R Corvette endurance race car uses a modified LS1 bored and stroked to 427 cu in and makes over 620 hp. You can buy a street version of the 427 LS1 that makes 585 hp. What I was saying is this 2002 ZL1 Camaro should be called a LS6 Camaro (it has a LS6 engine) and a modern ZL1 should use the 585 hp 427 cu in LS1. It is all too confusing with the new and old engines using the same number/letter codes. I think a 585 hp 427 LS1 2002 Camaro would do justice to the ZL1 name and would allow Chevy to showcase the GEN III motor while giving a memorable send off to the Camaro name. IMO
