Olds and Buick Eights . . .
Cadillac and Olds often worked together but Buick hated them and tended to keep to themselves. In '49 Cad and Olds both came out with new overhead valve V8s which gave them some of the fastest sedans in the world. Buick had been using an overhead valve design on their straight eights for decades and had a reputation of building strong and powerful engines; some bus manufacturers even used the Buick eight in commercial applications. However, like most all straight eights the Buick was very heavy and wasn't designed to rev. The new Olds and Caddy V8s were much lighter and more powerful. The four speed Hydramatic was also quite a bit more responsive if not so smooth as the Dynaflow. The result was that in comparison to Olds and Cadillac from '49 to '52 Buick didn't have a chance performance wise. In '53 they introduced the famous "nailhead" V8 which was big and powerful, but emphasized torque over horsepower, most likely to make up for the sluggish Dynaflow. Buicks were still not as quick as the equivalent Oldsmobiles (or Chryslers with their hemi-head V8s), but they were no longer so slow as to be embarrassed.
