motor and tranny fit

Hey guys,can someone tell me what a 3800 motor and tranny from a 93 buick regal would fit into? is there a site to go to for this? My father in law had an accident and totalled the car off. the powertrain is 110% one owner always used synthetic oils,tranny always flushed and filled with new filter every 30,000 miles. car has 120,000miles thanks john

it should fit perfect into any other car with the exact same engine. if it's really a 93 then you don't wanna put it into a car that's any year later since they have different computer systems. this is of course if you're only swapping the engine and transmission w/o the ecm. so the years you want to look for are 91-93
here's a list of cars that had this engine:

buick lesabre
buick park avenue
buick regal
pontiac bonneville
pontiac trans sport
olds 88
olds 98
olds toronado
olds sihouette

i dont' think you'll have issues with the transmission since i don't think these cars came with electronic transmissions until 94.

Thank You for the info. now to find a good body. A hunting we will go.
