Get precise, easy-to-read timing mark alignment with this adjustable chrome steel timing pointer, sized for 8" diameter harmonic balancers. The adjustable design lets you fine-tune pointer position for accurate timing checks, and the chrome finish keeps the front of the engine looking clean and finished. Timing pointers are balancer-diameter specific — verify your harmonic balancer measures 8" in diameter before ordering, since a mismatched size won't read timing marks accurately. Hardware is not included with this pointer. ApplicationsFits Chevrolet Big Block V8 Gen II (Mark IV): 6.5L/396, 6.6L/402, 7.0L/427, 7.4L/454 in³.
