So I recently just purchased a 1986 Caprice Classic. After I take of the Maintenance ie tune up tires etc I was looking to but a 383 stroker under the hood. But before I do that what are some things I should get replaced before i think about putting any new engine in the car. I want the car to be a daily cruiser but has to have the power/speed to keep up. Any help can will be appreciated since I am kinda new to this car scenery thank
