Motor and tune,that's pretty much all you need,everything else will fit.

Where in so cal are you? There's a lot of people down here who could help you out. But like someone said, just the motor and that's it. You'll have to adjust the tune but that's simple enough to do.

Does it matter whether its lq4 or lq9 I know it's about a 20hp difference but I'm planning to switch the heads,cam and small things here and there

They are basically the same. However here's some differences I pulled up from previous threads on here:


LQ4 and LQ9 are Gen3 engines, not Gen4 (like the LS2, LS3, L76), due to the location of the cam sensor and knock sensors.

LQ4 debuted in 1999
Displacement was/is 6.0L
1999-2000 had iron heads
Compression ratio was 9.5:1
Block was Iron

In 2001 the LQ9 was introduced
Both the LQ4 and LQ9 shared the iron block and new 317 heads (similar as the 243, but with larger 76cc chambers), hence both are 6.0L
The LQ9 had 10.4:1 compression ratio, versus the LQ4's 9.5:1
No longer did either 6.0L require the crank adapter for the trans, now works with LSx applications.
In 2004/5 6.0L recieved improved rod design

In 2005 the LS2 block was introduced
It is essentially the LQ9 with an aluminum block
LQ9 still offer with an iron block.

The 99-00 will not bolt to a 4l60e. The 01+ lq4 received a shorter crank that mates directly to a 4l60e, and with a spacer to the 4l80e. LQ9's never came behind anything other than a 60e/65e so you don't have to worry about removing a spacer if you plan on using a 60e tranny. Compression on the LQ9 is 10.08:1. The only differences between the 4 and 9 is beefier rods and flat top pistons in the LQ9. The rods debuted in the 02 LQ9 are the same as LS2 rods. In 05 all lq4s and lq9s received the same internals sans pistons.

Are you looking to do it yourself of pay someone to do it? I can recommend you to a shop that's in the SFV that will do it for a reasonable enough price. Or to some people that might help you for some beer money but that's between you and them to figure out.

Then engine itself I would like to be done by a good shop , since it is my daily driver, as far as minor work I would try to do myself or have someone help me

PM BlownChevy. He has a shop in Chatsworth called supercharger connection. He knows and can do an engine swap fairly easily. Not sure on his prices but he's one of the more competent people out here in the valley when it comes to LS stuff. I don't have his shop number and not sure he want's his cell number out in the open, but here's a link to one of his deals, just PM him. I think he's a sponsor on here.
