Correction: The performance hoods were optional for 318
Challenger/Barracuda starting mid-production 1970. 318 cars with this option had no emblem-locating holes on Barracuda
or Challenger.
EDIT: The Challenger J54 - Sport Hood was never offered on 318 cars. Only Challengers with 340 or larger engines could receive the J54 hood and always had engine size callouts.
Cudas with 340 for 1970-1973 got the
`cuda340 emblems. Cudas with 360 for 1974-only got the `cuda360 emblems.
Maybe someone else can fill in details on whether a BH - Barracuda could option a 340 engine for each model year. I know there are JH - Challengers that did get 340 engines in the A66 package at least for some years. Others on this forum have expert info on which years a base Challenger could get a 340 engine.
Those answers would assist in determining if a 340-equipped base model Barracuda or Challenger would need to option the performance hood separately and get engine callout emblems or not.
1970 Power Bulge hood offered on all model Barracudas with J45 Hood Pins mandatory.
