1. Here is the motor where we last left off. The lower end was together, and the pistons were installed. The cylinders were slid down over the piston and rings, then the motor was rotated to position the piston to top dead center (TDC) to check for any clearance issues. We were getting ready to install the heads and rockers, then build the S&S throttle body and install the S&S air cleaner kit.
