LS3? L99?

I have a 2010 SS with auto trans. How can I tell which motor I have in my car? The LS3 or L99? I was going to call the dealer with my vin and ask but was wondering if there was any other way.
Thanks

Auto trans = L99 400 hp
Manual trans = LS3 425 HP

Have fun

I think the LS3 is 426... But 1 HP is like tomato / tomatoe... :)

You have the L99. L99 is the LS3 with AFM I believe.

The L99 has a different cam, lower compression, different valves and relief cuts in the pistons vs LS3

I believe all auto trans are L99 and all manuals are LS3s.

Yes, the AFM blows until you take a road trip!!!.. But I used the paddle shifter.. They seem to off set the AFM..

Also,
the LS3, Manual has a "W" code in the VIN

The L99, Auto, has a "J" code in the VIN

True, but that's at the crank, at the wheels its really more like 0.8 HP

Not exactly. There are considerable differences. (L99 is quicker - :biggrin: )
