Correct. The 429 was offered in three variations:
429 Thunder Jet - basic 4V
429 Cobra Jet - performance
429 Super Cobra Jet - high performance
The 429 was unique in many ways. It offered:
- Thin wall casting
- Longer bore centers than the FE block
- Huge bearings
- Canted-valve cylinder heads forming a slightly hemi-spherical combustion chamber
- Rocker shafts were replaced with rockers riding on fulcrums with separate pedestals

It was first offered in the 1968 Thunderbird (Thunder Jet). Later on it became the Ford 460. It is not part of the FE engine class: 427, 428
