2 more rare Pontiacs are the 350 Pontiac powered '77 Bird, running SS, & a '74 350 powered GTO, running SS.
I only know of one of each. The '77 Bird was raced by Sal Piacentini. Mike Morgan bought it & has raced it for the last several years.
Of course, the SS GTO belongs to Bill Rink.
Both cars have won class at Indy. Mike has been RU to Bill, at least a couple of times. So, these 2 cars are both rare & quick.
In 2018, the Bird was quicker, qualifying @ #11, but Mike waited too long to leave & lost the SS/MA class win to Bill.

No, '77 Birds & '74 GTO's are not rare. But as 350 powered Super Stockers, they are indeed rare.
