As will become familiar practice with many positive-displacement blower installations on Coyote 5.0s, you must perform some battlefield surgery on the timing cover. Three ribs are notched, two bosses are flattened to rib level, and one boss is half-trimmed to rib level. The FRPP instructions are quite clear how to do this, so be sure to pay close attention-measure twice and cut once! Also, be sure to tape up the cylinder heads' intake ports and cover the valley before you start slinging aluminum chips. Then carefully vacuum up the mess before you start installing the blower kit. If you buy one of FRPP's forthcoming Aluminator 5.0 long-blocks, the timing cover will already be modified for you.
