I thought a while back I'd be parting with my 1995 Cadillac Seville STS (Northstar 4.6) for good due to some pricey repairs. I'd love to keep it, though, and have the engine replaced. I need to know if a 1996 Deville engine would fit into and work with my car, as I may have access to one. Does anyone have some insight into this? Thanks!
