is there that much feel or differnce in power between the lq9 and lq4? also hom much would be needed to make and lq4 to an lq9? last hom much did you guys get you 6.ol for and where? thanks

 

Lq4 Has Dished Pistons, Lower Compression, And I Believe That The Lq9 Has Floating Wrist Pins And Possibly Different Heads.

 

most of it can be made up with tuning. the big difference is compression. 1 point of compression is really nice- but its not a show stopper.

edit:
rods are upgraded too


The LQ9 version of the 6.0L that was used in the Escalade and Silverado SS came with the 123/145 casting that had a thicker beam, a stronger big end and a bushing in the small end for a full-floating pin.






The 6.0L pistons were all flat tops, but the ones used for the 6.0L LQ9 that came in the Escalade in '02 had a moly coating on the skirts and a thermal barrier on the top.


All of the Gen III pistons have had a moly coating on the skirts since 2003.




the LQ9 had something cool in the crank, cant rembmer what though.

You wont notice a difference.

 

can a lq4 be made into a lq9 with the cange of pistons and rods?

 

for the most part yes. I have both a LQ4 and LQ9 and the only difference I noticed was the pistons and rods.

 

do you know how much the rods and pistons would be?
