L77 engine with/without AFM: with/without VVT?

Post by VintageIron41 »

Hello-
Texas Speed is telling me that 8th digit vin code 2 denotes an L77 engine without AFM and with VVT. This is new to me, thought code 2 just meant L77 engine. I asked them for more details, they want me to inspect valley cover to confirm and I understand the VVT timing cover is deeper, all hard to see without disassembly, are there any other clues to confirm AFM and or VVT?

Thank you!
