57-58 not sure-forgot! Olds 371 eng with hydro. Motor ran very good when I removed it years ago. Currently pickled & I spin it very often. Was saving for a model A build but, not happening. Motor is complete with ps pump, carb ,dist, ex manifolds, fan , pullys etc. I`m asking $500.00 You don`t see these often in ready to go cond. I would clean & repaint & use. This is for LOCAL pickup ONLY!!! Please email me if interested at [email protected] thanks! Located in CT
