1991 cadillac V8
 

I have a 1991 cadillac brougham it has the 5.7L in it and I am going to put the engine in a 2002 chevy S-10 and I was wondering if anyone could tell me how to find out if the engine in the cadillac is a chevy engine or if it is a buick,pontiac, or cadillac. I am also told that it is a detuned LT1 not sure though. If the engine is a chevy engine it will bolt right into my truck if not I need to get all new brackets. So if any one could help me with this information it would be greatly appreciated.

All smallblocks (RWD V8 engines for that matter)in the GM cars for the 90s should be Chebbys no matter what since I think olds-Bui-Ponti-cadillac discontinued their RWD V-8s in the 80s. Not exactly sure on the year though, it could have been 1990 (at the latest probably)for all I know when some ofthe V-8s of othergm companiesstopped productionso don't quote me on this. But yeah the transplant should be easy considering its Chevy to Chevy.
