yep - Buick. I was "economy option":lol2dfx said:Don't you mean the 231 V6? A buick 4.1? Never heard of it!
It looks as though you are correct.vanaisa said:´81 De Ville had three engines
- Buick´s V6 252cid, 125bhp
- troublesome V8-6-4 368cid, 140bhp
- and optional diesel engine - 350cid, 105bhp
I guess the 368 was never offered any way except in the V8-6-4 configuration.Standard engine for DeVille and Fleetwood Brougham was the "modulated displacement" 368 cu. in. (6.0-liter) V8-6-4, with digital fuel injection. Optional: a 252 cu. in. (4.1-liter) V-6, provided by Buick. That V-6 had Computer Command Control and a knock sensor to adjust spark advance, as well as diagnostics. The Olds diesel V-8 was also offered.
