Will McLearran has fully prepared this block for assembly. All machine work and cleaning have been performed. Close inspection is next before assembly begins. Our block has been bored 0.030-inch oversize and finish-honed for proper ring break-in. Because this engine will be turbo-charged, a lot of thought has gone into machine work and assembly. Piston to cylinder wall clearance is critical because piston temperatures become higher whenever we start driving cylinder pressures skyward-which happens with forced induction.
