Going farther back, the 1970 Chevelle SS396 CID was actually 402* cid (396 over-bored). The SS396 moniker was so popular (1965-69), they were afraid to call it SS402 and lose sales/cred in performance venues. The 402 put in non-SS cars was marketed as  a 400 Turbo-Jet even though they also had a small block 400 Turbo-Fire available in many non-SS models. 

 

*Prior to 1970 GM corp would only let engines of 400cid (or more) in the Corvette and the big cars.  That's why all the muscle cars (less COPO) were under 400; 389 GTO, 396 Chevelle, Camaro etc.

Then there was the switch from to 400 Pontiac motor to the 6.6 L (403 CI) Olds motors in Firebirds which disappointed enthusiasts.
