okay i have run into another problem with my swap. the back of the crank sticks out just a bit farther than on my 4.8L, so now what i have bolted the flywheel and clutch all together and now it looks like my starter wont catch the flywheel. lookin for any help yall can give me thanks.

 

this is common with the lq4 since they are mated up with the 4l80.. i havent heard of this with a lq9 thought because most are with 4l65e... On the lq4 there is a spacer on the crank that needs to be removed for it to work right..

 

i was sold this motor under the impression that it was an 03 escalade motor, i.e. an lq9. the back of my motor looks like this....

Thats an lq4 with the long crank.. you may have to try and make some kind of spacer or something.. Do you have the 317 heads??

Here is mine..

 

yeah i have the 317 heads thats why i didnt question weither it was truly a lq9. my 4.8 looks like yours in that pic you posted. i that post i referenced it said that the motor was a 99/00. so that motor would have had a different starter than the newer lq4/lq9, right? how could i tell for sure weither i have a lq4/lq9 without removing the heads? and i already have the motor in the truck and the trans bolted up.

 

yes my friend had a different starter and with the 6 speed i really think the only thing u can do is change the crank

 

are you sure that the spacer on the back isnt removable??? my lq4 is a 01 and it had the shorter crank.. not sure why a 03 would have the long one.. Its not the starter that is your problem, it is the longer crank..

 

no im not sure, it means ill have the unbolt the tranny and all the other stuff to find out i guess. unless someone else knows for sure. thanks for all the help. ill take it apart and find out what im lookin at and let you know how it comes out.

 

if i were u i would try and get a bore scope and see if you have a flat top motor (lq9) not a dish piston (lq4).then i would get a starter to fit and make sure that their is no problem with the clutch clearence.

 

Well im hoping it turns out to be something easy.. Good luck on getting it all figured out.
