If they do continue the ZL1 nameplate it will be with a smaller DI engine that hopefully makes the same power. The current ZL1 will be the last of the "Big Blocks" for quite some time.
The current ZL1 is not a big block, it is LS small block. You probably meant the end of the big cubic inch motors. and i agree with you,because of the stringent MPG they have too meet by 2013, GM is going to smaller cubic inch engines.
