69 383 cuda value

More information required.

Is it a Cuda' or a Formula S? Cuda' would be more desirable.

Is it a 4spd or Auto?

Have you looked for the broadcast sheet? Under the rear seat, carpet of above the glovebox to name few.

Does it have all the BB pieces? radiator, exhaust manifolds, chrome valve covers etc.

If it is like mine I thought it was pretty solid with the exception of the obvious. Once blasted there was a lot more rust than could be seen. The aftermarket has new metal but it can get costly to install it.
