GM Trucks and Cadillac's V12 are supposed to be the 1st with cylinder deactivation, so I doubt the LS4 is for the Monte. Very possible, but I doubt it.


It's pretty amazing the information that ends up on this board.

 

Yeah but 327 ci also converts to approximately 5.3L , so let's just call it 327 for old times sake???

Anyone have any ideas on hp?

 

In the Silverado the 5.3L V8 is 325cid

 

Niiiiiiiice information. So the highest displacement was decided to be 6.4L and not 6.6L or 7.0L. Now I just want to know what cars those engines will go into!

TWIN TURBO V12??? What is THAT going to go into??? An Escalade? Make the worlds fastest and most powerful SUV by a LARGE margin??? I can really only see that engine going into a super sports car. Figure that it will produce 500hp in base form, add in 8# of turbo'ed boost and you're running 750-800hp. That's a little much for your average SUV.

 

Here's the complete list of RPO numbers

It would be worthwhile to look through this for other tidbits that it may hold.

 

Well... ZR1 is on the list ... "Performance Package" "Special Coupe"

 

look at RPO code M97 is that a tranny brake? also, why does this list still have some old stuff like the syclone and the typhoon?

 

I imagine the 6.4 LS7 will be for the next gen (C6) Z06 (or whatever its called).

 

Hmm, perhaps this is list is just what GM has though of/tinkered with... there's an alcohol I4 on there too..

 

Since the Gen IV V8s are an evolution of the GenIII do you guys think it will be an easy swap with an LS1? or do you think it will be more like the chachge over from the LT1 to the LS1? I'd love to get a 2002 SS and put a LS2 or LS7 in it assuming I could get a create LS2 for just about the same price as an LS1, This would be something worth looking into.

 

Swapping engines in a 4th Gen = not fun.

 

The Caterpiller line up is interesting also...
