GM has recently released their 2012 Product Guide, which details all of the engines and transmissions used in production vehicles, as well as the specs of the engines. Several years ago, we used to outline these updates, but have been lacking in getting the information out for the past few years. In an effort to try to keep the site up on the most recent releases from GM, I am trying to get this information back into articles again. With that said, on to the information.

I am just impressed by the difference in power between the DI and standard injection. Granted, the CR is slightly less in the non-DI engines, but wouldn't think that would account for between 50-75 less horsepower. The low-peak torque for the truck versions is quite impressive as well.

I'm wondering if the LFX is going to become the Chevette swap of choice, if not it'll probably boil down to the complexity of the wiring and integrated exhaust manifolds. I guess I'll find out in a couple of years when the owners of these new Camaros start yanking those V6s and swapping V8s in.

almost in the range of low peak torque on a diesel with that.

i was noticing the difference in power levels with the different version of the engines before. same engine size wise but one was DI and the other was a regular one.
