A bit of clarification on the mid-'50's Buick specs. The "Fireball" V-8 debuted in the 1953 model year in all models except the Special, which still used the straight-8. Displacement of the V-8 for the '53 to '56 model years was 322 c.i. in the Century, Super and Roadmasters, and 264 c.i. in the '54 and '55 Specials. Special and Century engines also used a 10.5:1 high-compression variation for cars equipped with Dynaflow transmissions to give them a bit more grunt off the line, as Dynaflows were notoriously sluggish.
