Of all the unknowns about this car the engine, IMO, seemed to be the easiest to guess. The LS3 is no different than the L98, LT1, LS1 or LS2 before it. Despite the power these are just mass produced performance SBC's for this day in age.

As for power. If we look back at history and when the Vette and Camaro shared the same engine and trans the only "detune" was the F-bodies more restrictive exhaust and intake which gave GM marketing a nice option to rate the engine as less powerful but as we know that was not the case.

 

i agree, this doesnt seem like news at all, i think it was more conclusive when the G8 GXP was announced as having a detuned LS3, and since its built on the same platform as the camaro, it would make sense that the engines available to the camaro would be the L76 for the "base" V8 (z28?) and the LS3 for the SS. i bet they (G8/camaro) might even be priced VERY similarly.

 

but i believe that the engines are actually certified now, so they cant "underrate" engines anymore.

 

I am not as educated on the GenIVs as I should be, but what is the minimum octane for the LS2 and 3?

Although the LS1 was rated for 91+ you could run 87 in it if you wanted.

 

I think the number they give has to be within ~2% of the actual SAE rating

 

Every production motor has to be within 2% of the certified rating but the rating has to be within 1% of the test motors dyno output.

 

If I'm not mistaken wasn't the LS3 designed with AFM and the vette people actually made enough noise that GM didn't offer it in the vette.

 

AFM is not available for the Vette due to the fact that the exhaust work that it would require for a Corvette to sound like a Corvette in 4cyl mode would be too much for the underside of the car.

 

If the LS3 is 16mpg city and 26mpg highway in the Vette will that be comparable to the Camaro?

 

I would think that the final weight of the Camaro will factor in that equation.

 

You should have the option. Most new GM engines allow you to run high test or regular.

It cost about 20 HP in the Series III 3800 SC if you used regular and cause no damage.

 

Haven't heard that one. .

I have read that no DOD on the '08 Corvette had something to do with bad harmonics/vibration in the drivetrain on the Vette.

 

Has anyone here driven a vehicle with DOD?

 

I have.....a Honda Pilot, i dunno how you can really compare the two though Anywayz, the 4 cyl engine shut downs to 3 cyls when you maintain a crusing speed over 45 mph after about 7-8 seconds....Little to no hesitation in cylinder reactivation when u get back on the gas.......

 

Yeah my Tahoe has it, it is completely seamless in its operation.
