I know the new engine in the Sierra is rated at 380+ but its just as slow as the last model year which had alot less hp. How are GM engineers able to to make that much HP but its still slow. The 90's SS454 were rated at like 250hp but the still hauled *** compared to the new 380-400hp trucks. I realize weight has an effect but it shouldnt be that bad.
I hope the camaro engines arnt as lazy as the truck engines given the same hp.
I realize they need to keep the tunes mild but they should still haul *** at WOT.
Dont the 1/2 ton hemi's run high 14's 2wd to low 15's 4x4 and thats with lame DC programming.
I see these high numbers but still low performance.

You must be joking right? The Denali does a mid 14 second quarter mile. That engine-1000+lbs-brick aerodynamics=FAST CAMARO.
And the SS454's weren't really very fast at all, just brimming with torque to make it feel powerful.

this is what the average consumer knows:
Vortec series - truck motors

no consumer wants a truck motor in their sports car/muscle car.
and i want VVT in my motor if it's available.
why would i be pissed the corvette got the LS3?
thanks for strengthening my point.

i have a 2007 6.2L L92 i got off a escalade. know i'm looking to mate it with a t56. is it possible, is it the same bell housing as the ls2, and would the ls2 flywhhel and clutch fit the l92 (LS3)
and since the motor was an auto do i have to change the harmonic balancer now that i am changing the flywheel. thanx

I thnk you give the average consumer to much credit.. I doubt they can tell you the diffence between a Vortec Motor and and LS motor.. I.E. ask them what Motor goes in the trucks, you proablly get a blank stare...
^^Yes. It stands for Variable Valve Timing. I'm glad that the big motors are going over to this set-up. There is even a company that is modding the LSX block to work with the L92 VVT cam.
I think it would be badass to put the cam phasing on an on/off button. Show the car, even turn it on, sound like a tiny-stock cam, then BAMMM flip the switch and you have a huge cam!!!
It could also work as a gas saving function. Roll around town or even DD on the small cam, and have the big cam for racing only.
If only it would be that simple.

yes but is it that simple? wont our motors become big overweight machines that will not be as good as they are now. thats what makes us so great right? light weight engine that is simple. none of that vvt or 4v garbage
you do realize that thats not they're motor anymore? i mean it is but thats not the one they're all drooling over. they have a 5.7 vvt DOHC V8 thats putting out 381 HP and like close to 400 Ft/lbs of torque. they are nice I'll admit. I work with them all day pretty peppy and torquey but the Cartridge filter, and 8 freaking quarts of 5w20 and 0w20 in some places is REDICULUS and 12-16 miles is not my definition of a good motor.
on the other hand, I seriously would not be surprised if the new Camaro gets the LS3, I mean look at history. the Camaro got TPI like a year after the Corvette, it got the LT1 before and it got the LS1 before the Camaro, two things you can bet on one thing, there is a motor the Camaro will never see. the LS7. if you remember the Corvette got the nice LT4, and was a conversion for f-bodies and other LT cars. they kind of branched out with the LS2 a little, putting it in different things but the Camaro was discontinued then so kind of hard to say on that one. but again if history repeats itself then i would not be surprised if the Camaro gets the LS3 for its V8 option or like a SS option
someone correct me if I'm wrong, but didn't some Northstar motors have Variable Valve Timing? I know the new hybrid Chevy's have it but I thought some of the older Northstar motors had that as well. and they're efficient. VVT isn't just for the ricer boy's domestics use them too.
