Trans-Am info for the 1966 Barracuda

Has anyone built, or is in the process of building one of these cars?

Does anyone know what engine they ran? Was it the 273, or was it something else?
In 1968 or so I worked on a Trans-Am Barracuda that ran in the San Francisco Region SCCA Series. It was an ex-factory car and had been acid dipped to make it lighter. I'm almost 70 years old now, so I probably have lost a few details and what ever I say should be taken with a grain of salt, but here goes. The engine we used was a 304 CID. Some calculator work can verify this. I think it was a 273 block with a 340 crank. Remember the class was 5 liters or 305 CID. I think we ran a 4 bbl Holly on a high-rise manifold. The headers were full length tube and what I always complained about was that they were almost half crushed under the car because it was so low. I can't remember the owners name, but it seems he could not afford to replace the exhaust system. The rear end was a 8-3/4 Sure-Grip modified with Lincoln Continental discs. I think it had 4.10 gears. The doors were welded shut, and people were always pulling on the handles so the handles stood out about a half inch or so from the thin door panel. All of the glass was faired in with body putty. This car at the time was what I called Petty Blue, and I want to say it had a white racing stripe over the drivers side, but it's been too long to be sure. In my opinion the operation was under funded and I never saw it run well enough to decide if the driver/owner was talented. I was associated with the group for about a year, maybe less, then moved out of the San Jose area. With a growing family at the time I soon had other priorities.

After reading through this whole thread, I remember that we had FIA documents on the car and every component was called out in the docs. The oil pan looked stock from the outside, and had a windage try in it.
Good luck on your project, it's interesting, that my previous project to the Barracuda was also a Formula Vee.
