Freddie has sent me several records sheets (thanks) and that is helping the effort. Trouble is, they are the cryptic "69 Chevy" style so you have to guess at model/engine. I am getting pretty good at it.


But here is one for any gurus:
June 1971
H/S Gary Moore-Carroll's Auto Service-Pierson Pontiac, Tulia, TX
114.06mph, Houma, LA May 71


So I am ASSUMING the car is a Pontiac but they don't even give the year. A 70 GTO 400/350 fits but that is a total guess.
Web search discovered nothing on the car.
Anybody recall?

Thanks!!
Google just needed that one extra word:


http://www.hotrod.com/cars/featured/...tiac-firebird/


Gary Moore of "Acre Maker" cars:
71 Firebird 455ho/335hp
12.22-114.06 h/s



Ok let me push my luck a little, here is another mystery car:
65 Winternationals
Corky Schroeder
"Pontiac" (no year / model / engine)
14.23 at 98.57 E/SA


Any ideas??

Found this entry list for the 1965 Winternationals, but just lists entry as a 1960 Pontiac. Number 760.

Here's an 'Acre Maker' '61 Pontiac.

Gary Moore, Tulia Texas. Great guy, Gary and Ann still race. He had that '61 Ventura when we met them, I was driving a stock one like that (color and all) to work & back at that time.

Thanks Terry even that hint helps. Only 2 cars really fit, assuming there was no factoring yet:
60 Cat 9P wagon, 4360/363hp=12.01
or
60 Ventura HT, 3966/333hp=11.90 right on E/SA
So I guessed the Ventura, with prepped engine & trans, down at shipping weight, 1st try in the Gonkulator said
13.91 at 98.72
Closer than usual for a 1st guess!
I just cut down the traction G's a bit, that's all it took for
2.27
9.21 at 78.4
14.21 at 98.58
One of the fun things about re-visiting the vintage NHRA stuff with the Gonkulator is I can see about what 60ft time they must have run to jive with the rest of the combo and et/mph. 2.27 seems slow, but my daily driver cars Gonkulate to more than a 2.40 short time back in the 1970s based on the few vague scribbled timeslips I got back then. Sometimes only the ET was scribbled on the timeslip, not even the MPH! Tires were awful back then.

I wonder when NHRA "pulled" the 4-spds out of the '57 Pass Cars...what most of the
owners did...and how much slower was the car with either a 3-spd stick...or the PG?

From what I have learned from this thread, the HAMB Junior Stock thread, and Boyce's Junior Stock book, a lot of stuff was legal in 1969 but not in 1970:
* Chev Sedan Deliveries:
* Hydramatic ok in 1969
* Had to run iron PG in 1970
From the data I have, it looks like folks lost a couple tenths at first, but as the 4000-stall converters caught on the difference almost disappeared. The Gonkulator runs I am computing show about the same.


* Chev 57-58
* 4spd ok in 1969
* Had to run 3spd in 1970
* Again, maybe a couple tenths was lost though data is sketchy, I don't have any direct before & after.
* The Gonkulator calculates that most of the loss was in the shifter - the 3-on-the-tree was a LOT slower, but even on the floor, the 1-2 shift is fast on a 4spd but slow on a 3spd (unless you get clever with the shifter as some did).

I vaguely remember the rules change mentioned in the "Strickly for Stocks" column
in Hot Rod Magazine....also recall a Delivery racer with "NHRA hates Sedan
Deliveries" lettered on his car....
