For the new Zeta-based Camaro
-"Base" Camaro (Most likely): 2.8L 210HP V6 from the Cadillac CTS. It will keep costs low as they could use bits and pieces allready available, and lets them use the 6M transmission out of the CTS. Although the engine is smaller than the 4.0L V6 in the Mustang, they make about the same ammount of power.
- "Base" Alt #1: 3.9L 240HP V6 from the Malibu, Impala, etc. There is an available 6M transmission, so thats a plus. But I belive the engine was developed for FWD only, but that can be changed.
- "Base" Alt #2: 3.6L 255HP V6 also from the Cadillac CTS and Buick LaCrosse. Although it makes much more power than the V6 Mustang, it would position the Camaro as an alternative to other V6 coupes like the 325ci, etc. But the 3.6L is EXPENSIVE, and I somewhat doubt that it will be the choise
* The V6 powerplant is probably what GM is worried most about. Considering that they will sell just as many V6 models as V8s, it is important for them to consider when building the car a few years from now.
-Z/28 #1: 5.3L vortec 5300 Flex-Fuel V8 320HP. Allready utilized in the Tahoe, and soon in the Silverado, Avalanche, etc. the engine is well known for a good ammount of power and pretty decent fuel economy. Using E85 will be a good move for GM, and the Camaro could become a Flex-Fuel flagship for the company. This would probably be one of the cheapest ways to make the Z/28 as there are so many of these engines built every year.
-Z/28 #2: 5.3L LS4 303HP. Baisicly the same design as the Vortec 5300, the LS4 is slightly smaller in overall size and uses an aluminum construction as opposed to iron for the Vortec. Used in the W-Body SS and GXP models, the engine is pretty powerfull and would be a good match to Ford's 4.6L V8 wich down about 3HP and 3lb-ft of torque.
-Z/28 #3: 5.0L V8 using the Vortec 5300 block and 4800 crank, thus creating a modern version of the infamous 302 V8. It probably wont happen, but I wouldnt put it past GM to build a 300HP high-rev V8 like what was in the origional '67 Z/28s.
*This is also debateable, but the safest bet will probably be the LS4 or Vortec. They can both be adapted to accept a 6M transmission, so we will see what happens.
-SS: 6.0L LS2 V8 400HP. You almost would have to be retarted to not see this one comming... Its easily the most adaptable and trasferable engine GM has in it's lineup, and you can be certain that the Camaro will have an option box with the LS2 listed.
- SS #2: A larger version of the 6.0L LS2, probably closer to a 6.6 or so. 400HP is not enough to chase down the Cobra, so more power is needed. GM is known for developing specialty versions of different engines for specific models, so again I wouldnt be surprised to see a modified version of the LS2 (similar to how the LS1 and LS6 were related) to push in the neighborhood of 450-475HP.
*Here is the problem: Does Chevrolet want to let the Camaro play with the "normal" Mustangs as well as take on the top-line Cobra? Or do they want the Corvette to handle that job?
- COPO 427 Camaro: 7.0L LS7 V8 505HP. Depending on how crazy Ford gets with the SVT Cobra (along with the rest of the specialty Mustangs), I wouldnt be surprised to see limited eddition COPO Camaros being made. They only built a couple hundred, maybe a thousand a year back in the late '60s, and they could easily do the same and turn a profit. The only problem is, the COPO Camaro could start stepping on the Corvette's toes, and that is something GM would not let happen anytime soon.
-------------------------------------------------------------------------
-"Base" Dodge Challenger: 3.5L Magnum V6 250HP. The Dodge will need more power because of its is heavier platform than the Mustang and Camaro. Used currently in the rest of the LX cars, it can be assumed that the new LY platform that will replace them will be just as accepting to the current engines. The only problem is, Dodge no longer offers a manual with any of their V6-powered models... That may be a problem, and it may not
-Challenger R/T: 5.7L HEMI V8 340HP. It's Dodge's "bread-and-butter" V8 and can be easily adapted to the new LY platform. Again, more power would be needed to make the car as fast as the Mustang and Camaro, and the HEMI is the only V8 that has the "juice" to get it to do so. This may encourage DCX to develop a manual transmission option for the HEMI, so I'm all for it.
- Challenger SRT-8: 6.1L HEMI V8 425HP. Same as before, allready being used, easy to adapt, yadda yadda yadda. Makes good competition for the Camaro SS, but isnt enough for the Cobra.

Of course, it is all speculation, but it makes sense...
