OK, there were major changes in Stock, for the '72 season. So, I'll wrap this up where the Jr. Stock book records end. It has the race results thru the '71 season.

That means there could have been some '71 model year Pontiacs racing, during that last year of Jr. Stock racing. Hey, I suppose there could have even been some '72 models racing, near the end of the year, where tracks were still open, after the new models were available.

Anyhow, the 455 was now available in some Birds, Goats, T-37's, GT-37's, & probably several other models. Compression was lower, than in '70. BUT, the round port head 455HO was available. There were probably quite a few 455HO powered cars ordered especially for racing.

I've read that the '71 #66 D-port 455 heads were poor flowing heads. But, the 197 455HO heads were good, basically RAIV heads with bigger chambers, to reduce CR.

Since all the cars pictured below are '71 models, I can't guarantee that any of 'em actually raced during the '71 season. But, I assume that some did.
