if youre referring to an ls3 yes ive seen them in a few late model GM EFI vehicles.

 

That crate motor cost more than its worth, it's compression is to low for a N/A motor, and it doesn't have strong enough rods for a high boost F/I build.

 

waist of time buying a crate motor like that, do yourself a favor and look for used ones for sale plenty of people swapping them out of new camaros and vetts for bigger engines. I have a ls3 in my car and its pretty strait forward.

mine was built for a ls1 computer so I didnt need a converter box but you will need one if the engine has a 58x reluctor wheel which is stock on ls3s

you also need to drill and tap holes on the side of the block for the knock sensors, sounds seriouse but its really easy and takes a couple minutes, you also need a cam sensor extention harness (be carful alot of these are wires wrong and you will have to switch the 2 outside wires if you throw a cam code after install.)

you will need to extend the map sensor to front of engine if your using a ls3 intake, if you use a fast intake you can keep it in the back.

also if you use a ls3 intake you will need to source a throttle cable bracket or make your own. using a fast intake will allow you to use the stock bracket. you also need a 4 bolt TB instead of 3.

you can use the DBW system if you get the pedal to go with it but i just kept mine cable.

other than that theres really not much difference in anything.

 

plenty of places sell all the harness extentions you need as a kit, as well as timing covor if engine does not come with it. everything else bolts back in like stock just use all your same brackets motor mounts and accessories

 

Cool thanks for all the info.

 

Just as they said, it's a waste of time and money. Find someone who works for a dealer. Just for a reference for what this engine is worth, A friend of mine can get me a crate ls7 for a little over 3k.
