Brand new body lines brought crisp new looks to the full-sized 1963 Chevrolet Impala, Bel Air and Biscayne. Chevrolet was on a role and topped the production charts in 1963. The Chevrolet Impala remained the most exciting of the bunch with more luxury and options than one could imagine. While comfort wasn't the only thing on Chevrolet's mind - Chevrolet produced a new 427-cubic-inch competition V-8 that outran everything early in the season at Daytona. Chevy also aided its racers by offering dealer installed aluminum front bumpers and front sheetmetal. Still "real fine" was the famous 409, offered in three versions including a; 340-hp 4 barrel, the unchaned 409 hp and the new solid-lifter-high-compression power house offering 425hp.
