yeah the current owner wasnt happy with the motor and plans on doing a 350 tpi swap instead of tuning the 383, anyways i got the heads up about it and bought the motor back and i even pulled it from the car myself, a little weird considering it was about 4 years ago that i put that motor in myself. And as of now i plan on doing a quick rebuild, bearings, rings gaskets, etc and changing the cam and intake manifold and with some fine tuning it should be at the previously planned 500 hp.
