Is there any difference in an L35 out of a 2WD versus 4WD? The guy sellin the motors said the oilpans are different. Will an LB4 oilpan (my stock one) bolt on to an L35?

Yes, the pan itself is different but it actually bolting to the engine is exactly the same. The 4wd pan has a hump in it to clear the diff, that's the only change.

Re: UPDATE!!! Quick L35 question!!

Went and got the L35 yesterday. It came out of a 2001 Envoy 4WD. The oil pan bolt patterns are COMPLETELY different. The only holes that line up with my stock pan are the rear main studs. All the others are no where near close, you can't even see any of the holes. Really baffled me why GM would change the pattern.

The good news is its a pretty simple mod to the aluminum pan to make it work. We just have to grind off a trans line mounting lug and a couple of fins to make a room for the turbo return line fitting. When we get it done I will post some pics of it.

L35 was made from 92-95. You bought a Vortec L31. You will find the heads don't bolt up either to your stock intake. You should do a search on E-RUE and his late model Vortec swap.

Ahhh I see, that makes more sense. I have converted Vortec heads and intake so I'm good to go on those. Good stuff to know though. Thanks guys.
