1STTEXAN Posted December 31, 2011 Report Share Posted December 31, 2011 What are the differences, if any? Between an '06 SSS 6.0 Vortec and a '07- SSS 6.0 V-Max? Quote Link to comment Share on other sites More sharing options...
RCNap12986 Posted January 17, 2012 Report Share Posted January 17, 2012 There are a lot of differences. For starters the block of the newer 6.0 is aluminum. It has displacement on demand and the new style rectangular port cylinder heads (L92). I dont know the exact cam specs but I think the newer engine has a smaller cam. The new found power comes from the better flowing heads. It is also tuned to run on 87 octane rather than 91 from the factory, which means it leaves more on the table for a tune. Both are stout, but if you have the choice I would get a newer one. Quote Link to comment Share on other sites More sharing options...
T-Bag Posted January 18, 2012 Report Share Posted January 18, 2012 Are you referring to the NNBS 07's or your "classic" 07? The LQ9 6.0's are all identical from 03-06/07 Specs are 345hp at crank The L76 6.0 that's in the 07 NNBS trucks are rated 367hp at the crank Quote Link to comment Share on other sites More sharing options...
2001silverado364 Posted January 18, 2012 Report Share Posted January 18, 2012 (edited) You must be talking about the differences on the engine covers or something. All SS engines are the same, stock. GMT-900 v-max are a whole other story.I *think* the 05+ covers says vortec max and the 03-04 covers says vortec 6000.

jm3907 Posted January 18, 2012 Report Share Posted January 18, 2012 (edited) He's still trying to spot a difference from 06-07 classics! Edited January 18, 2012 by La SS (see edit history) Quote Link to comment Share on other sites More sharing options...

RCNap12986 Posted January 18, 2012 Report Share Posted January 18, 2012 I should have read more carefully... If youre talkin SSS to SSS then they're the same. I thought you were comparing the GMT-800 LQ9 to the GMT-900 L76. Quote Link to comment Share on other sites More sharing options...
