Chuck.
I did run the red bird Friday at their test and tune session. They would not let me run it during the Meltdown because of the rims even though they did have some prone to break down GM FED's without era correct rims run in an exhibition class. It ran 9.5's at 139 MPH. It has a 5.8 rear ratio and needs to be something lower for the 1/4, it must have been designed for an 1/8. I go thru the lights over 8000 RPM.
Charlie,
They have to look era correct from the stands but anything else goes. Most all of the cars have later then 1966 drive trains and they even use trans brakes at the line.
