Just to clarify, all lsx pans and pickups will bolt to the ls2, right? I've got a GTO LS2 with a front sump and would like to swap to a rear sump. Is there an online resource with pics, measurements and PN's of the different LSX pans and pickups? ATS also makes a rear sump ls2 pan correct? Thanks for your help.

 

I don't know of any definitive site that has measurements and part numbers for everything, but if you search you can find the dimensions.

The swap faq has part numbers:

I don't know about ATS, but the vette ls2 pan is rear sump and apparently much better than the previous ls1 pans. You also have to swap the windage tray and pickup tube.
I thought there used to be an oil pan sticky somewhere.

Here are some various pan dimensions:

Fbody:


CTSV (I think it's incorrect though):


GTO:


C6 picture I made:


Truck vs Fbody sump:


Try a search next time, this has been covered PLENTY.

 

You'll also need to swap the dipstick & dipstick tube too.
