Zero to 60 Run--4.6 Cadillac Northstar V8 vs. 4.9 OHV V8
Zero to 60 comparison between my new 2001 Cadillac Seville SLS with a 4.6 Northstar V8 and the 1991 Cadillac Sedan de Ville with a 4.9 that I've owned since 2005. The Northstar in the Seville is faster, especially at the top end, but the good old 4.9 in the DeVille holds its own--especially for an 18-year-old car with 257,000 miles on it.
Judging from the time codes in the video, the Seville did it in 7 second flat; the DeVille is just over 9 seconds.
Interestingly, both cars shift from 1st to 2nd at 45 MPH, and both hold 2nd gear all the way up to ~80 MPH. Without a tach in the DeVille, I have no idea how high it was revving, but it probably went close to redline.
The noise you hear besides the engine revving in the Seville is raindrops on the windshield. I had the camera on a tripod held down between my legs in the Seville; in the DeVille, it's just handheld, so it's shakier.
Both runs done on Stapleton Rd. just south of Monmouth/Independence, Oregon
Another Reason NOT TO BUY A NORTHSTAR 4.6L Cadillac
I don't know why a pulley that controls the top cams would be made of plastic instead of steel... but after the tree pull it sat for a week or two then this happened. I have since pulled the motor and started taking it apart for scrap... its a bad design from the start the heater core has a section that says CUT here for service... the headers on the back cant be removed without dropping the transmission. Tell me one good point about this engine!
