I thought all of the Motion cars were SS's, not Lagunas.
1973 was the last year for the Super Sport package on the Chevelle ( and '73 was also the last year for a 454 / 4 Speed combo , if I remember correctly ... ) .
The Motion-built '73 Chevelle* originated as a 454 / 4 speed (a rarety in its self !) . Its original purchaser was "displeased" with the lack of power from the LS-4 engine , so he opened his wallet wide ($16,000 in 1973 !!) and had the folks at Motion build a 427 , add the Hone-O-Drive , slide some trademark Corvette sidepipes on , etc. , etc.
A really neat-o ride !!
* = An SS model
