I worked for a Buick Dealer and we were able to order our own demos. Many of us drove Regals and when I saw the 301 was no longer available for '81, I started looking into the V6 combinations.
I was able to get a 3.8 with 3.08 gears, whereas the V8's only had 2.41 or so, with no alternative choices. My little 3.8's out ran all the other guy's 4.3 V8's, as well as the bigger 4.1 4 bbl. V6 in subsequent years, which also had no optional axle ratios.
That all ended in '85, when the 5.0 Olds motor came available in a Regal.
Still a dog, but it was all relative in the 80's.
