What’s included with the distributor and how is it assembled?

The unit ships as a complete assembly: distributor housing, cap, rotor and ignition module already installed. That reduces parts hunting and lets you perform a like-for-like swap without sourcing separate electronic components.

• Comes with cap, rotor and ignition module pre-installed.
• OE-type mechanical and vacuum advance, both adjustable for tuning.
• Built from standard materials to match factory durability and installation points.
• Packaged ready to install—no additional core exchange required.

How reliable is this replacement and what warranty does it carry?

THEBIGDEALS supplies the distributor as a brand-new aftermarket part with a limited warranty policy to cover defects and early failures. Support is available if you find a manufacturing problem, and the offering includes short- and medium-term protections to increase buyer confidence.

• 100% brand-new unit manufactured for direct replacement compatibility.
• 30-day warranty plus a 1-year unlimited replacement commitment.
• OE cross-reference numbers provided to confirm correct part selection.
• Customer service available for quality or fitment issues.

How do I install and adjust the mechanical and vacuum advance?

Installation follows standard distributor swap procedures: set base timing, align rotor to cylinder #1, install distributor and secure. Both mechanical and vacuum advances are accessible and adjustable to match factory specs or custom ignition curves for mild performance tuning.

• Install with engine at TDC on cylinder #1 and rotor aligned to distributor housing mark.
• Connect vacuum line to the vacuum advance port if used by your vehicle.
• Adjust mechanical weights and springs per vehicle timing specifications as needed.
• Recheck ignition timing with a timing light after installation and tuning.

Who is this for: This distributor is aimed at owners, restorers and mechanics working on late-1980s to mid-1990s Chevrolet and GMC V8 vehicles—especially C/K trucks, full-size Blazers, Camaros and similar models that need a reliable, drop-in HEI-style replacement. It’s useful for routine repairs, engine rebuilds or upgrades where OE cross-reference compatibility and a complete component set speed the installation.
