Oil pan alignment 1/4 off on one side 03 6.0

[cmcmanus365]

I bought a 03 6.0 lq4 used off a guy. I replaced the oil pan gasket and realized the passenger side of oil pan is 1/4" hanging off the block. Now the driver side is flush! Since the tranny bell housing bolts to the bottom of the pan and will effect transmission alignment. I'm wondering if the the pan is off the wrong motor? Anybody know how to fix this

Is it flush with where you bolted that engine stand to?  From the pics you posted, it looks flush with that...

ignore the flexplate its not bolted down, i only put it in there to see if the pan would hit the flexplate. i know the picture sucks but, in the top picture the pan and gasket sticks out past the back of the block.

The stand is bolted to the block, so yes the stand would be parallel to the block.

The end of the oil pan looks flush to that part of the block.

its not trust me, ill take another picture. The pan will not slide forward, any idea how to fix this?

So it turns out the pan is suppose to hang over the back cover plate. if you look at the where the bell housing bolts to the passenger side block from the side. The block is actually inline with the back of pan !

Yes, that was what I was trying to point out...

The oil pan on an LS engine must be absolutely flush with the rear transmission mating surface of the block.  That is because there are 2 bolts that bolt the transmission to the oil pan.  If the pan and block are not flush, either the oil pan or transmission bell housing will crack when you tighten the engine to transmission bolts.  This is why most LS oil pans have a warning about proper alignment cast right in the bottom.  Check with a straight edge or leave the pan screws loose until you mate the engine with the transmission, draw the pan back flush with the transmission, then tighten the pan screws.  The area on the right side of the block where the pan sticks out past the block in your first picture is where the starter mounts, that is not a concern.
