ok, built one engine, and now im left wanting more lol. so im in the market for a 6.0 but know very little about LS series engines, so can someone school me? what 6.0 to look for, and what would it be in to build and drop in my truck?

 

A complete, cheap, working one with a lot of extra stuff included.

 

i know this, i mean is there a better year? i here the lq9 is the best one to build up

 

lq4 would be better for boost. lq9 better n/a.

 

I can't tell what came in what, but what I do know is this.
LQ4 is far easier to find than LQ9.

IIRC, LQ9 came in Escalade.
Just a guess, but I'd say to look for either engine in heavy duty usage vehicles, like Hoes, Burbs, Escalades. Some vans or 1 tons may've had em, prolly had to be 2500's. Oh ya, what about VortecMax & SSS? 1500HD?

I know they came in some of the aforementioned, but someone else can detail yrs & specifics. better than me.

I haven't needed 1 yet, but if I did, I could tell u exactly.

 

99-00 lq4 had iron heads and a longer crank that cant be coupled to a 4l60, only a 4l80
01-04 lq4 came with aluminum heads and can be coupled to a 4l60 or 4l80
05-newer lq4 came with aluminum heads and the stronger rods that were in lq9's and can be coupled to a 4l60 or 4l80
all lq4's had 9.4:1 comp ratio
lq9's had the stronger rods aluminum heads, but with flat top pistons for a bump in compression ratio to 10:1

if i was going n/a i would pick up an lq9, for boosted i would go lq4, and if i was looking for an lq4 it would be an 05 or newer

 

Well, there ya go. Did u know those from memory?

I also think he wanted to know which or what came in what model & the year. If he didn't, I'd like to know for grins.

 

Trucks with engine vin code "N" denotes the LQ9, which were available in 02-06 Escalades, 03-07 Silverado SSs, and I believe later nbs model silverados and sierras with the VortexMax option.

 

what could a lq4 be built to?(horsepower wise) and still be streetable

 

4-500?
