LS3 and L99 Cutaways
Been lurking for a few months, but I thought I'd break the ice by introducing you to the LS3 (Top) and L99 (Bottom) in the nude...sort of.

Hmm... WELCOME - first, and second, I wonder what's with the valve reliefs in the L99...
Thanks

We need a lot more information on the L99. I've been trying to figure out a lot of the new stuff. It looks so much like other LS-series engines with a few unique features.

I'm with you there, but I'm wondering why? I believe the LS3 has a lumpier cam so why is it the L99 has them?

I bet it's so that if the afm gets stuck and holds a valve open it won't make contact with the piston. I know you don't want to miss oil changes with the afm or use the wrong oil.

look at the cam gear on the L99. WAY different, i wonder what it does? maybe some sort of clutch the advances or retards the cam. I think ill call it Variable Valve timing and patent it
