Title: Shelby Guru Question Individual Throttle Bodies on GT350's
Post by: Benny on October 16, 2021, 05:37:39 PM
Were any 1965 or 1966 GT350's raced with individual throttle body weber induction units. If so would anyone have any photos?

At least one 66 Trans Am car was raced in the day with Webers

The 1965 R model delivered new to the Comstock racing team in Canada ran webers back in the day.

Shown in use is a late 1963 through about March 1964 system using Weber 48 IDM5 two choke (a.k.a. venturi) carburetors.

Canadian rules permitted the Webers.

I wouldn't be surprised that the carbs were messed with and an "old-timer" liked the earlier carbs? Notice the different fuel like routing in the two pictures.

There was still a lot of Voodoo going on with them, even though it was largely imaginary.

The whole underlying reason that there is a Shelby GT350 in the first place is Ford wanted a race on Sunday sell on Monday Mustang.
The Mustang was a B Production car and was not competitive against the SB Vette without both chassis and engine mods.
Production rules at the time allowed for engine mods or suspension mods but not both.
By being listed as the manufacturer Shelby was able to produce 100 modified cars to satisfy SCCA production rules.
All the cars got the suspension mods and then race car engines were modified further but keeping their overall published specs such as single carb.

  Mike ,
      I know it's not your picture but I have to call foul. If this is an r model , it would at least have an export brace instead of the the stock braces , right? Also of not is the super long dip stick/tube , as in ''generator" application.

Several cars were raced under the Comstock livery in period, including a Mustang two door hard top.

Hi Dan, would it be fair to say, no 65 or 66 Shelby GT350 was raced in the SCCA in the USA with webers? However a mustang coupe with webers was raced in Canada through Comstock racing?

GT350s racing in SCCA B Production during 1965-66, the GT350 historians need to answer that one.

It would be fair to say no 65/66 GT350 raced in SCCA in the USA back in the day with webers. They were illegal to run in that sanctioning US bodies venue. Canadian venues allowed them and historical documentation indicates that the Comstock team car used them . Most likely other privateer cars used them in racing the Canadian venues also.

The Comstock GT20350 that had Webers installed when delivered had earlier 48 IDM Webers and not the 48 IDA Webers that you would have thought would have come on that late of a application.

Just as an update and additional information. The picture I posted in reply #1 was as that car was raced outside of the US

When I saw the x-Bob Johnson 289 Cobra in '82. Ken Eber owned it and it had the IDM's on it.

Ken would say that it was the first Cobra to win a race. I never checked to see if historically it was raced with them or not?

Back then I can't think of anyone who was delineating between IDM's and IDA's. People would just say "Webers".

Most of us were just novices with them.



When I first saw William Wonder's GT40, #103 in '75, it had Gurney Eagle heads with Webers on it. Now I wonder which ones?

It always seemed that there was a secret security guard around these cars that were going to hit you with a stun gun if you even just asked a question so one had to tread lightly.

shelbydoug, your quote " It always seemed that there was a secret security guard around these cars that were going to hit you with

a stun gun if you ever just asked a question so one had to tread lightly"


here's my photo of Wonder's GT/103 at Mosport, Canada, 1966. Is that the secret security guard sitting in front of the

car with a beer in his hand   ;)

I  don't know, he's secret.

I was only around Wonder once. He wasn't an issue. Norwalk '75 or '76. The car was dark blue then.

As a matter of fact, the GT40 people have always been pretty good and laid back. Not like the Cobra folks who circle the wagons to protect them from the "Indians". I think that was Watkins too? I got cut off at the pass!

I remember Watkins Glen in '91 or '92. We were walking through the pits and "the" three Mk II's were there. My 4 year old had to touch the black one. Like a physical exam from a Navy doctor.

I asked him not to and he said, "that's ok Dad. If I break it, Grandma will buy it". Now watching this entire scenario was George Stauffer that cane over to me and said, "Don't worry about it 'Dad', it's a race car" and winked.

Now the one Brit with the "Gulf" was entirely different.

Everyone in racing isn't like Nicki Lauda. Many are great personable folks who enjoy the crowds and every car isn't as cosmetically fragile as a Cobra.

I remember one convention where a nice fresh red 427 had a nice big hand mark on it from being unattended and a "photogrpher" leaned on the car to take a picture of the cockpit. So I do understand the paranoia to a degree.

It could be me. I have to stop carrying around Green Peace activist signs and put down the 5 pound sledge hammer?

Maybe that's why Eber blocked me at one convention from going near Shelby saying, "I forbid you to go near him"? Yikes. Carroll wasn't so afraid riding up the elevator at the hotel with us though? Then again he was more interested in talking to my wife, but that's another story. ;)

Yes. Those were the three that finished 1-2-3 at Lemans with Miles leading and Mclaren declared the winner.

I was told that was the first time they were together since the event but the colors were changed.

Stauffer was with the black one.
