I am going to be going to a junk yard and searching for some 6.0's, i haven't decided if i want the low compression 6.0 or the higher one, depends on what i want to build it for. But as i recall, the LQ4 is the 300hp lower compression motor and the LQ9 is the SS 345hp higher compression CORRECT??????

Anyway, i know you can determine which motor from a vin, but shoping for just the motor how can u tell which is which? Is there a block number i should be looking for? If someone could just let me know that would be great, i used to know and had the numbers written down but have lost them

 

it will say 6.0 on the block. There is no way to tell if it is a lq4 or an lq9 just by looking at it though. You'd have to check out the pistons.

 

Damn that sucks, i guess i would have to try and find out what vin truck it came from.

 

LQ9 only came in SSS and escalades i believe. The LQ4 came in silverado 2500s, some 3500s, full size vans, and a couple other vehicles i believe.

 

i think my buddy said that this tow truck company his friend has is gonna hook both of us up with SS 6.0's, hopefully for around $500. I'm debating when i get my motor what to do with it, i don't know if i'm gonna put it in my truck, or sell my beast and buy a rcsb. Also, don't know if i want to keep it a 6.0, i really want to do a 408 N/A, but that will take extra coin.

 

fwiw the lq9 came in the VHO as well

 

sucks that you can't tell what model 6.0 it is at the junk yards

 

if i find out what the vin number of the truck was, what are the vin numbers that associtate the lq4 and lq9? U and N or something like that right?

 

First, I gotta believe that the 6.0 (or 408 ) would be a whole lotta fun in a regular cab truck but having it in your current truck would be great, too! Good luck with your project...I really envy you; I can't wait 'til I can put a 6.0 in my rcsb!

 

Well my drivetrain is pretty much ready for a bigger and better motor, hopefully with some FI. I envy the rcsb guys, i hate the ecsb now. That's why i am debating buying a stock 4l60 and TC and putting my truck back to stock and using my 4l80 and TC and putting it into a rc, or sell the 80 and stall and go with the t56.
