Accurate ignition timing is one of the most important adjustments on any engine, and MSD's Timing Tape set makes it easy to dial in. The set includes eight different tapes sized to fit common harmonic balancers ranging from 5.25" to 8" in diameter, each marked off in one-degree increments from 14 degrees ATDC to 64 degrees BTDC and printed on tough, chemical-resistant material. The tapes let you read both initial and total timing accurately, since total timing is just as critical as the initial setting.
