Is the 6.2L engine in the Camaro the same as the 6.2L engine in the Siverado pickups?

[GOMD]

Basically, but with some different internals, compression ratio and tune, I think.

Seems the engines are similar but different in HP/Torque ratings at different RPM settings. The weight of the truck is the killer 4,920 lbs. Plus your driving a box type front end vrs a refined arrow dynamic muscle car. Pickups do have power.

Different intake and exhaust manifolds

Yes of course but he was just asking about the engine. Might as well throw in the rear end, fuel system, injectors etc.

[oldman]

um dude the intake and exhaust manifolds are part of the engine.

I think it would be closer to a C7 Corvette engine, which shares the same name. The base Stingray makes the same amount of power and 5 lb-ft more of peak torque.

But even then, they have differences such as different exhaust manifold, where the C7 has a basic 4-to-1 collector while Camaro has a tri-Y design, probably for better scavenging. According to GM, 20 percent of the components of the Camaro LT1 is specific to it.

I am assuming the Corvette exhaust manifold didn't fit the Camaro for whatever reason, which gave the design team an excuse to completely redesign a new header for the Camaro. It seems like they had to have had a good reason to create a one off unique header? What does the 6.2 truck header look like?

I'm not sure if gm releases the hp and torque plots anymore but I have seen one for the LT4 somewhere. Since apparently the Camaro headers don't change the output at all, since the claim is that the extra 5hp and 5lb ft of torque on the Corvette come from the Corvette NPP.

I believe the Camaro LT1 has ULEV status so not sure if the Corvette, so maybe this is the justification for a one-off Camaro header?

Not sure about about the internals, but I would guess the heads are different, maybe the camshaft as well. Of course the tune.

Trucks are designed to serve a different purpose, torque is king over actual power output for towing.

I'm sure the exhaust manifolds are different due to packaging issues.

As 6spd said the shortblock are the same. The intake manifolds are longer runners and have a higher profile in height- more torque. The Camaro exhaust headers are unique. So they have the same cam, compression ratio, heads. The tune is different which affects VVT timing etc.

Nope they are the same minus the intake manifold. The VVT Cam timing is different in the tune to make use of the Truck intake.



Side note, From what I have seen I doubt there is much difference between the Vette manifolds and Camaro Tri-y for power because the exit side of the Vette manifolds are a bit larger then the Camaro's headers. Then GM neutered the Camaro Headers further with the Cat pipes that neck down under 2" before the cats. With the cat pipes deleted they likely are very close maybe a slight edge to the Camaro.

As I own both vehicles in question and as said, the main engine is the same on the truck L86 6.2 to the Camaro SS LT1 6.2.

The intake manifold is different, the HPFP and injectors are different, and the exhaust manifolds are different. The tune is changed as well in order to try and move the torque down lower where the trucks need it for towing.

[UnknownJinX]

Then I don't know why they did the tri-Y design. Packaging makes sense, but IMO tri-Y is probably more expensive to make than a 4-to-1 exhaust manifold.

And well, they have to cap the Camaro power to be slightly less than the Corvette because Corvette. It's just not as bad as it was in the past.
