All engines were again V8s as in previous years, now called "Trophy" engines. rather than "Tempest" (including the larger 421ci "big bore" engine). Standard engines are two-barrel units rated at with the three-speed manual transmission or with the optional Hydramatic, with a regular-fuel-capable "economy" V8 offered as a no-cost option with the Hydramatic. Offered as extra-cost options were more powerful versions of the 389 including a version with a four-barrel carburetor or Tri-Power option. New to the options list were two higher performance versions of the 389, including a four-barrel unit and a Tri-Power option, both with higher, 10.75:1, compression ratios. A engine was offered to drag racers. Late in the 1961 sales season the Super Duty was released for sale as a dealer installed engine. The 1961 models never came from the assembly line with the 421ci engine; instead it was a specialty item installed and sold at the discretion of individual dealers.
