273-2 performance (or lack there of) question

67CudaBob,
So what's the rest of the story? Do you still have it?
I do still own it. After the car got here, I stopped by a local Mopar shop with it, and the guy knew in seconds that is was the wrong linkage setup, and that was keeping me from wide open throttle. I ended up swapping on an LD4B manifold and an Edelbrock 600 carb and played with the timing a bit and the combination of those things woke the car up considerably.
