Hmmm... I think the Bonneville, Catalina and Tempest had the 389 c.i. tri-power options? I once owned a '63 Tempest wagon that I used as a commuter car. It was pretty rough looking but mechanically, pretty unique. It had a 4-banger 194. Pontiac took the higher-perfomance 389 and sorta removed one bank of cylinders. This motor was a 4-cylinder 194 with a 4-barrel carb. Ya don't see too many 4 cylinders with 4 barrels. This thing also had a shift-on-the-dash auto transmission. Can't say that I miss this particular vehicle!
