The biggest engine GM makes for vehicles(gasoline) is the 572
The biggest engine made by Chevy is a ls1
454.
Possibly suzuki? Idk if it is the biggest, but their Hayabusa engine is pretty insane.
That would be a matter of opinion. My opinion would be in favor of Chevrolet.
Chevrolet is by itself. Other GM makes can be interchanged with each other, but not Chevy.
