Much speculation on the new C6 has been going on. Mervzs (a user on CF seems to have inside information. Here is the GM RPO codes for several new engines. Ones to note are the new LS7 and the LTS and LTT

I like the sound of the 7.5L DOHC Turbo V12 <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Call me a ricer <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> but whats with that alcohol powered 4 banger listed?

Also, never knew the LS1 based truck engines were actually give LSx designations too.

Perhaps this is the line of engines that Cadillac has been developing for their supercar. I know its supposed to be a V12 that uses a similar design to that V16 they put in the Cadillac Sixteen concept car that toured the auto shows this year.

Hmmm....interesting. Should I start prepping my engine bay for the turbo V12 now? <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

all of the 12cyl engines have "VVT" on them, is this variable valve timing?!? <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

I would love to see the look on a ricer's face who says well just wait till my vtech kicks in, and someone responds with that motor <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

A 4.125 bore GM block would be awesome!

6.4L, is GM finally going to come out with a factory 4.125" bore block that is interchangeable with ours AND is affordable? <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Why are there engines on there they no longer make?

Displacement on demand is also listed on a few of them (cylinder deactivation)...

yeah...the fact that the LT5 is there is rather odd. I was under the impression that the crate motor is no longer available. Seems strange. And a 6.4 could just as well be a stroker as a 4.125" bore... weird.

I hope some of them do happen. As far as lt5, notice it says ohc and not dohc. The lt-1 was made from 70-73 then revived again as the lt-1 again in 92.Same with the ls6. Who knows?? A ohc ls1 would be sweet. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />
