93 allante, eldorado and seville...correct me if i am wrong
original specs on the bigger Northstar: 295hp/290lb-ft
The standard models (eldo, seville) still used the 4.9L, the touring models had the Northstar.
In '94 models, the standard cars offered the Northstar with 270hp/300lb-ft.
The 95' + std and tourning models went with the 275 and 300 horse Northstars respectively

Just to add to what Chuck said, the '93 Allante w/ Northstar came out in Spring of '92.
The Deville Concours had the Northstar in '94, and the base model Deville had it in '96.

Intake camshaft profile is different on the L37 cars (the 300hp) vs. the LD8 cars (the 275hp). That, and computer reprogramming to match the profile change. That's the difference in the engine. The Touring models also have a 3.71:1 final drive vs. a 3.11:1 final drive in the Luxury models.
I wouldn't doubt it. Oldsmobile always has been a leader and innovator in the field, even if they never received credit. Did you know that Oldsmobile designed and created the Quad-4 engine? By the way, the "Quad-4" is a 2.3L engine, IIRC. The dual cam 2.4L is probably just a corporate engine, possibly based on the original Quad-4 design.
Dude, enlighten yourself with a copy of the book "Setting the Pace". It's about Oldsmobile's first 100 years of history, incuding their development of the original Quad-4 engine. A GM corporate engine is always based on a particular design. Example, the "corporate" 3800 is based heavily on Buick's 3.8L V6 engine from the 70s and 80s. The "corporate" 305/350 during the mid 90s were based heavily on the Chevrolet small block engines. What you call the "corporate" Quad-4 was developed by the Oldsmobile division in the 1980s.
Here, let me paraphrase for you...from pg. 411 from Setting the Pace:
For all its problems in the 1980s, Olds could still play "innovator" quite successfully. The Quad-4 engine is a case in point. It was born in 1981 as one of several programs seeking a viable replacement for the traditional V-8 in light of new mandates for even cleaner air and higher fuel economy. Chief engineer Ted Louckes was instrumental in the Quad-4's development: "We could see the demise of the big V-8...and we felt it was important that Oldsmobile have an engine of some substance to replace that.
Obviously, that's far from the whole text on the issue, which spans some 3-4 more pages of the chapter, but it's the first page, so to speak, of the history of Quad-4 development.
