360 Rebuild for 1974 Swinger
So you are going to prelube this with a drill to make sure you have oil to both heads and to see that it has oil pressure. I would mark each pushrod with a sharpie. Then as you prelube it and turn it over by hand, I would want to see that each pushrod is turning. I would usually do this before the intake was on and make sure each lifter is rotating as you turn it over by hand. If not I find out why the lifter isn’t spinning. A little late to the party, but if they don’t spin I don’t run it. You can probably look through the head and see if the lifter is rotating.
