What was your source of information??
Sorry, I don't want a p1ss1ng match. They're different. Check out:

Junkyard Find: 1983 Oldsmobile Toronado Brougham Coupe
Never seen a Nova with the engine feeding a THM325 longitudinal "chain drive" transmission feeding a differential between the front wheels (forward of the transmission). Or anything like the wide weird frame that fit around this "Unified Power Package" drivetrain. Or independent rear suspension. Check out that junkyard pic of the underside of the Toro in the boneyard. Control arms, crossmember, sway bar, nothing like any Nova I've seen.
Anyways they were very front-heavy, especially with the 5.7 diesel. I always thought they were neat for their uniqueness and concept . . . but I also understand where their reputation came from. The THM325 transmission was based on the ill fated THM200. The 3.8 turbo had some reliability issues in the hands of people who wanted to drive an appliance. The 4.1 V6 had head gasket issues. The Olds 307 V8 was okay enough. Then there was the 5.7 diesel version. Those 5.7'* were hard enough to work on with the transmission competing for engine-bay space. I remember the neverending stream of diesel Sevilles coming through the shop. It always amazed me that such a top-line car could be that noisy and broken and smelly all the time. Not that I dislike diesel, it just didn't fit the stereotype of Cadillac IMHO .
