The Gen IV isn't really a upgrade, Besides the displacement it shares so much of the same architecture. In fact the cam in the LS2 is the same cam that is found in the 01 LS6 ZO6. Sure the L92,LS3 and LS7 head design is better but again the other 90% of the motor is based on the LS1.

Correct, not a total redesign of the Gen III to Gen IV, but enough advancements in AFM, VVT, as well as other small technical moves to improve the engines performance. The new heads make the L92/LS3 and LS7 breaths more life into a great and well built engine.

Also GM sold over 140,000 Camaro/Birds in 94.The last year for 100,000+ F-Body sales. It wasn't until 1996 that the F-body was in talks of being canned

My point was this, that if 4th gens had the same V8 engines as a Third gen, they would have fallen on there face after 93, and 94 would have been there last year.
Fbody has come near the chopping block several times, almost as many times as its almost gone FWD.
