Can I swap the Engine and tranny from a 1988 Olds Delta 88 to a 1992 Buick Regal?

Some mounts will certainly be different, but I think the bigger issue is the electronic/computer controls the 92 trans has . Harnesses and ecu's will be different.

I know around here they dont let you swap a motor from an older car into a newer body.

As long as they are the same engine groups/family, with the same displacement, and emmissions standards, that is illegal. Thankfully you can update a erly Gen 2 3.8 V6 to the latest Gen 2 stuff with out going further then the long block.
The long blocks are exactly the same from a say 89 Gen 2 to a 97 Gen 2. Charles

The engine should not be a problem, as long as both are either Gen 1 or Gen 2 FWD 3.8's. The transmission might not interchange, due to different mounts and electronics features. Your best bet is to viset a salvage yard and see if their Hollander Interchage boooks say they can be swaped.
On the engines, if they are the same gen, you just need the computer, emissions, intake (compleate), and such off the later year engine. Charles

Blackjack,
Physically the entire power train will drop into the front cradle of a '92 "W" body using the "W" body mounts, accessories, etc. - - - BUT, having said that, I would not do the swap.
The 1988 3.8L is not a Series I engine - it is kinda a transistion engine between the older 3.8 and the 3800 Series 1. Think of the 1988-1991 motor as a 1987 "C" code engine with a balance shaft. As that old joke goes, it is neither fish nor foul. Actually a good motor (as are the 86-87 roller cam 3.8s) but enough different that swapping them into newer bodies gets weird (hey, even swapping an '88 engine in an '87 body causes ECM problems, primarily with the Mass Flow Air Sensor system and the digital EGR).
Back to swapping the '88 engine into the '92 body: first, engine ECM electronics are not compatible between the '88 engine and the '92 body. Second, the ECM for that car also operates the transaxle (4T60E): the only "electronics" in the '88 440T4 is the lockup torque converter, so we've got that issue of compatibility.
Don't know what state you are in, but in CA that swap would be illegal UNLESS the car can meet 1992 emission specs (CA law is you have to meet the specs for the body year or engine year, whichever is newer).
Your best shot for that Regal is to find a 92-95 3800 out of any of the "W" body cars (Regal, Grand Prix, Cutlass) and go that way, BUT if you can't find a 1992 engine, be sure you get the ECM assembly (or be prepared to move all the sensors, etc. from the old engine to the new one). Avoid any 3800 1996 and newer: they are OBDII cars and again, ECM issues.
