There's a 6.0 Vortec truck engine that was labelled L76 and was in use around the same time as the 6.0 L76 car engine which went into G8-GT.9C1fanatic wrote:I'm sorry. I was wrong. Maybe I was thinking about the L 76 but then again it's supposed to be a very similar engine to the L 77 I could've sworn I remember reading in GM high tech performance magazine that some of the L 76 engines in the G8 had some warranty issues with some type of cam phaser that was part I assume of the VVT system. I'll try to do my research before I post next time Sorry guys
The truck L76 has VVT, the car L76 does not have VVT.
L77 is just the car L76 with flex fuel capability added.
--It's dead easy to spot VVT on L Series engines because the front timing cover is thicker at the top, which pushes the water pump, harmonic balancer, belts, forward a couple of inches.
No VVT
With VVT
