I built a 6.0 LQ9 after I shot a rod through side of my 5.3L. I used some of my parts and some 6.0L parts I came by to build it. Now I need to reconfigure the computer from the 5.3L to run the 6.0L. Right now I'm looking at a 2005 LQ9 from Silverado SS. I believe it also has the 4L60E.
So what parts of the Silverado SS / LQ9 configuration should I look at copying over to my old 5.3 configuration?
Bit more on my build. Note this is a 2001 gen 3 setup in Z71 Tahoe I'm working with.
- LQ9 bottom end balanced to within 1 gram.
- Vinci performance camshaft 578/587/213/220/114+4A
- Dual Valve springs to match cam
- Johnson 2116LSR lifters with custom pushrods from Manton
- Cleaned up castings / 317 heads otherwise stock.
- Intake manifold and throttle body from 2001 5.3L w/ factory 24 lb injectors
- Stock exhaust
- Stock 4L60E and converter
Will be building a 4L60E w/ 5 pinon planetary, upgraded shells, stronger clutches, shift kit etc. For now running factory transmission though. I may want to dial back power on shifts or do something to preserve the transmission till I can get the new one built.
Build is a low end grunt / torque motor and not so much a peak horsepower machine. My first startup video below using 5.3L factory tune:
