Engine options remained unchanged from the 1964 model year, with a 389 cu in (6.4 L), 333 hp unit being standard, equipped with a Carter AFB 4-barrel carburetor. A 421 cu in (6.9 L) engine was an optional upgrade. Both engines had choices of Tri-Power multi-carburetion setups and higher compression ratios. [15]
