I'd like to know this as well... I also would like to know if the speculation that the L76 engine has the L92 heads on it is true, and if so what size valves are fitted. I have just bought a pickup with the L76 engine fitted, and would like to know what i am dealing with. I am planning a cam swap, 1-7/8 - 3" headers and dual 3" system with cutouts. any speculation on a cam for best results?

Is the L76 truck engine the same as the one coming in the G8?

The truck L76 has a cam phaser right? The G8 promo material does not mention the cam phaser.

Everything I have seen the heads are the same on the V-max L76 and L92 I have the same heads I haven't compared the casting numbers though.

And intake maybe cam and less cubes and a different tune.

Default L76 output

the GM specs of the L76 are

CAR- 362HP at 5700RPM and 391ft/lbs at 4400RPM.
Truck 360HP at 5200RPM and 380ft/lbs at 4000RPM

probably a diferent cam in the 2 engines, but not much diferent.

Wow, the car motor makes more torque than the truck motor! Hopefully the truck has more down low and more than the car at the same 4000 the truck peaks at.
