Edelbrock Part # 7343 Hex-A-Just True-Roller Timing Chain Set. Use a hex wrench to dial-in your cam by simply loosening the cam bolts and turning the adjuster. Made from induction hardened billet steel, it allows for a quick cam timing adjustment to plus or minus six degrees.

Notes: Never hammer directly on chain or sprockets. You can crack the hardened links and pins and cause early failures.

Use a sleeve for installations that require hammering, a brass drift punch may be used if you carefully alternate blows on either side of the sprocket to avoid cocking.

Never stretch the chain with a screwdriver.

Check for clearance between the timing chain and block and between the chain and front cover before reassembly.

Be sure that both cam and crank sprockets are exactly in line with each other. Misalignment can cause chain to break
