I have a 06 lq9 and im gonna run my nv3500 for the time being. im in the process of putting the motor in and now i need to fix this before i go any further. My question is my flywheel im using from my 4.8 is touching the oil pan on the lq9. Do they make some kindof spacer or something to fix this? The crank on the 4.8 has a longer snout than my lq9. Any help is greatly appreciated!

 

I believe that the 99-00 4.8's had a longer crank like the 6.0's did (at least the ones with manual transmissions did), so yes, you will need a crank spacer. I don't have the part number, but I do know that there is a crank spacer available from GM

 

I figured it was either a spacer or get a newer model flywheel.

 

I guess that either would work...honestly, I'm not familiar of anyone running a spacer with a flywheel now that I think about it a little more, only with a flexplate and auto, not saying that it doesn't work or hasn't been done...

 

i think the flywheel outa a 02- 5spd truck is what hes needing
