I still have that magazine.
In fact most back to 1968

Dan Fahey,, I have the complete SS&DI collection, as I'm sure many others on here do.
I'm also pretty sure many of us have extra copies that could fill in the holes in your collection, if you're wanting to do that,, heck, I've got 4 copies of the #1 Nov.'64 issue alone. Think about it, as your Classracer family can help you fill those boxes,,, and of course there are the swap meets and Ebay. My collection lingered up in the attic for about 30 years when I went and brought it out to look at, and realized I was only 28 issues away from having them all, as I bought occasionally off the magazine stands in the '60s and started my subscription in '74 until the end of the mag in May of '99. It took about a year and a half to pull it off, so it can be done. They're all nicely bagged and boxed nowadays.
Sorry for the momentary hijack, fellas,, I love the SD Firebirds too,, in fact the car in the photos does resemble Stock Eliminator champion Brad Burton's red Firebird, but I believe he runs a 400 combo.

1973 Firebird Specification Sheet

I know my sisters Formula SD-455 was listed at #3470 lbs. or so
for Shipping Weight, and with the NHRA HP 'factor' of 345 HP
it just fit into E/SA.

Freddy Moore ordered a new Formula 455 SD thru Bendall Pontiac Alexandria, Va. in 1973 . I went with him to pick it up and he let me drive it home which kinda surprised me. If it had been me I would have wanted to be the first one in it. It was plain Jane white with black interrior and (4 speed). Little did we know at the time it would be only one of ten. Well it went thru all the changes most purpose built race cars go through. Starting with headers,slapper bars and slicks and ending up tubbed and converted to Trans Am skin for class advantage. There's a lot more to the story but bottom line it was sold off and God knows where it is today or if it still exists. I have a feeling it's a bracket car somewhere with a rat motor in it and the guy has no clue what it really is.

Seems that as I continue to search for Pontiac info I keep running across old threads I need to bring up.

While searching for info on the Herslow & Morlock '73 Trans Am, I ran across this thread. One of the posts says that the car set the E/SA nat record, in 1975.

But, here's why I bring this up. I have 3 pics of the car, before it was SD455 powered. It was still running G/SA, & had "455" on the shaker, which would indicate a D-port 455 engine. But, after they added the lettering, and it was still running G/SA, some of the lettering said the car was an NHRA Nat Rec Holder.

Therefore, does anybody here know when that G/SA record was set, & what the ET/mph was ?

The '73 SD455 Formula cars ran in D class, cause they were lighter than the T/A. John Clegg won D/S @ Indy '73, in his '73 SD455 Formy. But the '73 SD455 T/A's ran E class.

Any help finding info on the G/SA record for the H&M T/A would be appreciated.

EDIT: After I posted this, someone on a Pontiac site said NHRA put the '73 SD455 T/A's in G/SA, at 1st. IF this is true, then it's possible that the H&M '73 T/A WAS SD455 powered, when it was marked G/SA. IF this is so, then exactly when was the hp factor increased enuff to make the SD455 T/A run E/SA ? Any help with exact info on this will be appreciated !
