what all is involved in doing a 5.3 to 6.0 swap? a friend of mine has a complete 6.0 sitting in his shop that he said i can have for my truck. how do you tell a lq4 from an lq9? do i need to swap computers? what are some pros and cons from a daily driving standpoint? thanks

 

It wont fit, you should give it to me instead.

 

well it depends on what year it is, before 01 will not work and after 06 (in most cases will not work). With that said 03-06 being the best a lq9 will have 317 stamped on the head where as the lq4 will have a 2** stamped on the head. It's a fairly easy swap just use your accessories I would put a cam in while it's out, and stall if your going that route. The 6 liter gets about 1 mpg worse than the 5.3 but didn't use passing gear as much I'd say for a dd I like 6 liter better

 

whats different about pre 2001 6.0s? he said he thinks it is a 2000 motor but isnt sure, he got it in a trade from a friend who got it from a friend who replaced it because it was "knocking" but ended up being a broken flywheel, not the motor

 

BTW he has the wiring harness, computer, all sensors, accesories, etc

 

i believe that in the pre 01 6.0 there was something to do with the crank, and i was told wont fit with the 4l60e i could be wrong, ive never tried it but its what i was told a while back. kinda think of it there was actually just a post about that recently if you look threw a few of the treads on the board now

 

Pre 01 it'll still work, you'll just need to get a spacer. Not a biggie. Check my sig, swap is pretty straight forward.

 

pre 01 will not hook up to a 4l60e period.

Just stick to the 2001 and up

 

not to mention pre 01 have iron heads

 

i dont know where you got this info but lq9 and lq4 have 317 heads.
