The Edelbrock RPM-Link adjustable true‑roller timing chain set (part 7338) lets you fine‑tune cam timing without machining or special offset bushings, offering +/-6° adjustment. Made from induction‑hardened billet steel, it is engineered for operation up to 6,500 rpm. The set installs like a conventional chain; follow installation cautions regarding hammering and alignment to avoid damaging hardened links or causing premature failure.
