Default Ls3 ?

Let me see if I got this right the LS3 or should I just say the 6.2l V8 that comes in the new Escalade that has 403hp. Is that basically the LS3? Does it have iron block or is it alluminum <- that might be spelled wrong.
Yes I tryed the search button couldnt find them.

yes... that is an LS3 engine or L92 engine with heavier valves and weaker springs on the heads, a truck style intake, and a smaller lift cam. It is the same alluminum block as the 08 vette.

Vette has a L76 or LS3 intake, better cam, better valves and springs on the heads, and a much better looking car to put all that in! LOL

Also:
LS3 has flat top pistons with no no valve reliefs = 10.7:1 compression.

l92 has valve reliefs = 10.5:1 comp.

LS3 has different (supposedly better) rings.

LS3 doesn't have the VVT or DOD yet. L92's do (most of them anyways).

LS3's are out. They're in the 08 Vettes.
Look in the LS3 stickies for all the info you want about it.
