mhaire86 Posted October 28, 2018 Report Share Posted October 28, 2018 (edited) Just purchased an lq9 out of a 2009 Denali to go into my 2005 Silverado z71. My truck currently sits on 20×14×35 mud tires.I would like to see about 500 hp to the wheel, whats the best cam and headers?

WantaSSS Posted November 1, 2018 Report Share Posted November 1, 2018 The engine out of a 09 denali is a L92 (6.2l) not a LQ9. If you have an actual LQ9 its iron block and has cast 6.0 on the front of the block with 317 heads and flat top pistons. Just a FYI Quote Link to comment Share on other sites More sharing options...
