the northstar was first offered...when?

[murdoc]

In my quest to buy a Caddy, there are ads showing STS's in the 93 and 94 supposedly with Northstars. I thought it wasn't offered until 95...so can anyone confirm this?

Thanks,
Murdoc

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.

Yep, all correct. In list form:

1993: STS, ETC, Allante
1994-5: All Seville, All Eldo, Concours
1996-present: All Seville, All Eldo, All Deville

In all cases:

STS = L37, 295/300 hp
SLS = LD8, 270/275 hp
ETC = L37
ESC = LD8
Deville (incl. d'Elegance) = LD8
Deville Concours = L37

Deville Concours got the L37 too. Not the LD8.

Yes, excuse me. I switched the two models by mistake. The Deville and Deville d'Elegance received the 275hp LD8 engine and the Concours received the 300hp L37 engine. I made the change above.

Just keepin' you on your toes

Thank ya suh! We all need that from time to time.

Between the DTS and DHS or basic Deville, what does GM do to get the extra 25 hp out of the DTS?

[jadcock]

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.
