I built this car on a 1965 Thunderbird with a 390 engine. The engine fired right out of the box and sat for years. Definitely a plus. I found that the drop down gear linkage was bent and didn't work. I bent it back into shape slightly, but I don't know how it was ever bent in the original packaging. Still having problems with the operation of the electric throttle, the throttle does not open n9 no matter how long the machine runs. Maybe it just needs to be adjusted.
