Yes, we've run a ton of LS engine articles over the past two years, and some readers are sick to death of them. If you count yourself among that crowd, what do you think of GM's other late-model V8, the Northstar? The front-drive versions are packaging nightmares, but later versions can be found in rear-drive cars like the STS, XLR, and SRX (a short-lived unibody SUV). We don't know much about them other than the obvious 4.6L displacement, DOHC architecture, and healthy 320hp rating. What can they fit in? Is tuning software available? We have no idea. Wanna see some Northstar articles? We can dig up the answers if you want. The engine has only 10 original miles, which makes us wonder what happened to the poor donor car. Maybe it was flipped by a cell phone–distracted, Cadillac-dealership sales guy.
