The EP-10TB is a specialized HEI distributor with an integral mechanical tachometer drive for Chevrolet Corvette applications where the factory tachometer is driven directly from the distributor via a mechanical cable. Corvette C2 and C3 models used a mechanical tachometer drive system rather than the electronic tach signal used in later vehicles, and this mechanical drive is integrated into the distributor housing on the correct side and at the correct location to maintain tachometer function after HEI conversion.
Without a tach drive distributor, Corvette owners converting from points ignition to HEI would lose their factory tachometer function — a serious concern for both concours restorations and practical driving. The EP-10TB preserves the original mechanical tachometer operation while delivering the full HEI performance upgrade: 65,000-volt coil, brass cap terminals, electronic ignition module eliminating points maintenance, and adjustable vacuum advance.
Manufactured under ISO 9001:2015 quality management. The EP-10TB is a specialized product specifically for Corvette owners — standard HEI distributors without the tach drive cannot be substituted in these applications without modifying the instrument panel. Individual testing for tach drive gear mesh, coil output, and module function.

Application scenarios
Corvette C2/C3 HEI conversion
Corvette owners converting from points to HEI ignition must use a tach drive distributor to maintain the factory mechanical tachometer. The EP-10TB is the correct unit for this application.
Corvette restoration and restomod
Concours and restomod Corvette builders need the tach drive HEI for a correct underhood appearance that maintains all factory instruments.
Corvette specialist shop supply
Shops specializing in Corvette service stock the EP-10TB as the correct HEI distributor for C2 and C3 customer vehicles with mechanical tachometers.
Installation guide
Identify whether your Corvette tachometer is driven mechanically from the distributor or electrically. Mechanical tach drive uses a cable connected to a port on the distributor housing side. If your Corvette uses a mechanical tach, the EP-10TB is the correct replacement. Disconnect battery, mark distributor position, remove old unit, lower EP-10TB into position, connect the tach drive cable first, then the vacuum advance hose and single BAT wire. Set timing with a timing light. Verify tachometer response before finalizing installation. Approximately 30-45 minutes.
