With an experienced team and a lot of data.
Little changed in the way of styling between 1968 and 1969 model years for the Chevrolet Chevelle, save for some minor tweaks. There were other model shakeups, though, like the elimination of the base-model 300 trim, leaving the 300 Deluxe as the entry level trim.
The 300 Deluxe was available as a two-door coupe, four-door sedan, and the Greenbrier wagon, a name taken from the old Corvair lineup. Buyers could also get the Nomad, which was a stripped-down wagon variant.
That left the Malibu as the only other trim. It was the upscale model, and was offered as a sport sedan, sport coupe, convertible, sport sedan, or Concours station wagon (which featured wood panel sides). The Chevelle was also available in pickup form as the instantly recognizable El Camino.
Base 1969 Chevrolet Chevelle buyers could select a straight-six, but popular options were the V-8s of either 307 or 350 cid. The latter could be had with output of either 255 or 300 horsepower.
The Chevelle SS 396 was eliminated as a standalone model (it changed to the Malibu SS 396), but buyers could still get the big V-8 engine as a $347 option. They could also select outputs of 325 hp, 350 hp, and 375hp. Later models in 1968 had their engines bored to 402 cu in, supposedly for emissions reasons. They were nevertheless still labeled as 396.
The rarest of the rare were the COPO Chevelles. Like the COPO Camaros, these could only be specially ordered from the factory with a big-block 427.
