02 6spd SS, lq9 swap, need tips and advice please Im looking to install a lq9 in my 6spd 02 SS and need all the tips and advice I can get.
Is there a particular year engine I should get?
Im 97% sure the stock ls1 heads will bolt on, am I right?
Most importantly do I need the wire harness and computer??
I was about to buy a engine from the scrap yard but ive come across some better deals elsewhere, is there anything I should look for with people trying to get over??

Everything will swap over. The only real thing you would need to do is drill and tap a whole for the alternator on the LQ9 block. No you don't need the harness or computer, use your current one. You will need a tune though. What exactly are your goals? Is your current motor bad?

I can help you out since I did the exact same swap. If you have any specific questions during the swap just shoot me a message.
Pretty much everything will swap over, except for the alternator. The LQ9 only has one of the alternator bolt holes you need, the second might need to be tapped.
Is this an LQ9 long block? If so you want to keep the 317 heads, they flow better then the 241's and have a stock compression ratio of something around 10.4:1 on your LQ9.

Pretty much any year LQ9 will work they all had the stronger floating pin rods . They will have 317 or possibly 035 heads which are a bit rare. These yield a cr of 10:1 . You do have the option to go LS3 top end since you have a 4" bore !
