Can't think of any major changes in '72 that changed Pontiac drag racing. The 455HO was still available in A-bodies & Birds.
Changes were mostly cosmetic. Bird grills were changed to a honeycomb hole pattern. The '71 rectangular fender vents were dropped.
For the A-bodies, the Judge & the T-37 were dropped. The GTO type T-41 front end changed slightly, including more recessed grills & fender vents, behind the front wheel wells. The 455HO engine was still an option for the GTO & Lemans, including the Lemans wagon. Gary & Charlene Wood ran a '72 GTO & '72 Lemans wagon. May have run 2 wagons. I have wagon pics showing both a regular Lemans nose & the GTO type T-41 nose. I read that they ran both a D-port & round port 455. Charlene won the Grand Molson race, in Canada. The wagon also won smaller races & got some class wins.
Out on the West coast, Larry Maxwell had a strong running 455HO powered '72 Lemans. A div 6 lady racer from Canada drives it now.
In 2008,Todd Hoven won a nat event & won the G/SA class at Indy, with a '72 GTO. He qualified #7 at Indy.

I suppose the most well known '72 Pontiac racer of this modern era is Brad Burton. He won 2 Stock national championships in the Burton 455HO powered '72 Formy.
Sonny Ray had one of the most famous '72 GTO SS cars. It won several big races, including David Rampy's 1st nat event win, at the '83 Cajuns.
Here's some '72 Pontiac Bird pics.
The '72 Honeycomb grills can be seen in some of these pics.
Love pic #3. It shows a small tire Super Stocker, with slapper bars.
Pic #4 shows Gary Moore at the World Finals, in what I assume was 1972. I attended that event in '73. It was my 1st time to see the Funny Cars. There were lots of 'em & they put on an awesome show ! I watched most of the Sat daytime Pro qualifying from the overhead walkway, shown in the pic. Whole lotta shakin goin on ! Lots of noise & lots of nitro fume tears. That's been almost 50 years ago. But it's an experience I'll never forget.
Billy Foder owned the car in pic #6. As you can see, it has T/A hood & fenders, but no wheel flairs.
The car in pics 7 & 8 is the same car as in pic #6. In those last 2 pics, it had the T/A fenders, but had a Formy hood. When it had the Formy hood, it belonged to Lee Bannister. He won some nat events with it, including the Gators.
