Default L92
Can anyone tell me the difference between an L92 that did not come with AFM and has the VVT deleted and an LS3? Thanks

The L92 never came with AFM, only VVT. There is a later 6.2L, I believe it was the L94 and it had AFM and VVT. Didn't I answer this on another forum? LOL

The pistons have valve reliefs cut on the exhaust side for VVT...so the compression is slightly lower. That's about the only difference.
