i have been looking around for a while and cant realy find any lq9s and if i do ther are 1500. i have found alot of lq4 with 80km for 800. the lq4 are the only ones i can find for a good price. should i get and lq4 its an 05 block and head and go from there putting cam and heads. what do you guys think get the lq4 or wait for a lq9. is the lq9 that much better. thanks in advance

If it's an 05+ block, the only difference is the pistons, the LQ9 being flat tops vs. dished for the LQ4, as I'm sure you know. If budget is a concern (as it is for most of us), I'd get the LQ4 and make up the compression with a smaller combustion chamber in the heads. If you ever decide to go with a serious boost setup and need to lower the compression, you can easily do so by swapping heads in the future

Lol thats what i would do too I'd honestly go Lq4
How's your 5.3 treating you?

Good point (Bud) on the boost part . But IMOP I would go with the lq4 and slap some 243's or 799's heads on it ! 1 thing that was brought to my attention when I was looking for a 6L. Was the the majority of lq9 come from sss and escalades wich tend to be mistriated couse of the popularity umongs hot rodders like our selfs ! Compared to an lq4 that might of came out of an 2500hd that neve seen past 5k rpm !

From an lq4 to an lq9 you can't tell tje diffrence unless you take the heads off and on both of the m the heads should have 317 stamped on them and it should have 6.0L in the front of the block and the back !

you guys think 800 is fair for an 05 lq4 with 80 km. its already pulled so we have to gess its 80k. i make sure it turs over.

That's not a bad price at all IMO.

How much is 80km like 50k miles ! If so sounds like a good deal to me ! But remenber its always a gamble when buying a used engine !

is there a way to know if it is a 05 block.
