The pan will crush the clay and show you exactly the distance you have. Basically, you don't want the oil pump to be touching the floor of the pan nor do you want it to be more than a 1/2-inch away. We were a little under the 1/2-inch spec so we reinstalled the pan for good. With that, the long block was complete and ready for phase two. We'll go into more detail about our recipe, how to install things like an intake and ignition system, properly break in the motor and how to make adjustments for max power next month.
