Looks like there are 4 Pontiac powered Stockers, in a 100 car field. Adam Strang is #21 on the Q-list. Scott Burton had the only Pontiac powered Super Stocker. He's #14 on the SS Q-list.

One of those Stockers is listed as a '77 Lemans, from my state. Not familiar with the name. But the last name is Larsen. Below is a pic of Jack Larson's car. Guessing it's the same car. Might even be the same guy, or one of his relatives.
