I have a 95 LT-1 Fleetwood and I have had a 1971 472 sedan deville. Both of those are much more powerful, the LT-1 giving me the best performance and mileage, but you could have balanced champagne glasses on the Seville hood with that 368. At full throttle, it was a whisper. The power was good enough to move the Seville pretty fast around town, with more flooring necessary to maintain highway speeds (no overdrive in 80). It is much faster than the 4100 and faster than the Fullsize 77 Grand Prix that I had with a 301. The only con is the fact that electronics, like the Throttle Position Sensor (TPS) is unique to 1980 and is not produced anymore. A NOS one is $250 and very rare. On another note, 1980 is a horrible paint year. GM used dispersion lacquer and it gets massive alligator cracks if you attempt to paint over it. The whole car has to be stripped to respray any part of it.
