Junior Stockers

The Jr. Stock book goes on thru the 1971 season. So, that means there were some '70 model Pontiacs which ran Jr. Stock.

There were at least least 2 big changes, for the '70 model Pontiacs. A 455 engine replaced the 428. It WAS available in the Goats, but NOT the Birds. It would be the ONLY year of a high compression 455.

The Firebird got a complete body style change.

Formula Birds got a fiberglass hood, with 2 long scoops.

Trans Am Birds got a "Shaker" hood/scoop, fender vents, wheel well flares, plus front & rear deck spoilers.

Some high performance Birds came with a 12-bolt Chevy rear end.

The 400 RA4 engine was still available in Birds & Goats.
