The motor I have is a Mopar 340 out of a 72 Dodge charger . I was told it has been sitting for a while, but it wasn't because anything was wrong with the engine, transmission had went out. What should I do before I start the motor, what kind of oil should I first put in it and what kind of oil should I run after the first oil change being that has come from 1972. Thanks, The BUCKSTER
