Are you sure you're not confusing the 60* V6 family that was around in GM vehicles in the 80s (the 2.8, 3.1, and 3.4 and their predecessor engines) with the Buick 90* V6 (of which the 3800 was a part of and dated back to way before I was born). Otherwise that's pretty fascinating...GM vehicles are always so strange in so far as that the "lower end" marques and lower trim vehicles always seemed to be better designed, more durable and way more reliable. It's hard to believe that Olds didn't just use an SBC derivative like the LT1 for the Aurora given how much better those engines were (and everyone knew it) than the Northstar, which was basically a flaming expensive pile of shit from day 1.
- Tanoc 2y agoYou're right that I got the two confused. The 3800 Series II was descended from the 1960 aluminum "Fireball" V6 and used a block derived from it's successors, but if I'm remembering correctly was part of the engine family that started in 1978 and was part of GM's downsizing to combat gas prices. The Fireball and 235 used a 90° bank and was 3.8L but with the switch to FWD in 1982 the new LK9 used a 3.0L (I was wrong about the 3.6L displacement, I apologize) 60° layout that grew in displacement until the late 1990s.
