6.0l needs rebuild suggestions for mpg
Hello all, first actual post on here!
The ride : '02 Yukon XL Denali AWD with Nelson Tune
6.0l has piston slap and now knock sensor is out.
So, I figure if I gotta yank the intake, I might at well keep going. I need some advice on any changes I should make while I am there, other than decking, balance etc.
I want as much mpg as I can get without losing power. Currently just fresh air, no other adds.
This is an LQ4. Should I go with the LQ9 piston?
Should I change cams, or will added duration bring down the mpg?
Prices are about 825 to 1000, less cam and probably bolts. Anybody got a lead on a cheaper kit?
Thanks in advance
Russell
