1961 chevy Impala project parts car rat rod chevy 350

Up for auction is a 1961 chevy impala 4 door sport roof hardtop project or parts car. This car has a motor and trans in it but i don't think it is the one that came with the car. The numbers on the back of the block are 3970014 i was told it is a 1968 350. The motor has a aluminum holley intake on it. I was also told the trans is a 400 turbo (i am not a chevy person) The motor does turn over by hand. There is a lot of parts that come with the car. From what i can see both the front drivers and passengers windows are gone. The seats have been swapped out with a later model impala seats and a console with a floor shifter. There is no exhaust manifolds but rest of the exhaust pipes from the manifolds all the way back is there. The car comes with a clear title. If there is any questions please ask.
