The Pertronix Flame-Thrower HEI/EST distributor is built for Chevrolet small block and big block V8 engines that use computer controlled electronic spark timing. It has no vacuum or mechanical advance because timing is managed electronically by the engine control module through the EST connection. A magnetic pickup and high output HEI module deliver strong spark, and the self contained design needs no external ignition box.

FAQ
What is an HEI/EST distributor?
It is designed for engines that control ignition timing electronically. The distributor has no vacuum or mechanical advance because the engine control module sets the timing through the EST circuit.
Is this a direct swap for a standard HEI?
No. It requires the computer controlled EST setup. Use a standard advance HEI distributor for engines that do not run electronic spark timing.
What engines does the D1020 fit?
It fits Chevrolet small block and big block V8 engines. Because it is designed around the engine family, no vehicle specific programming is required for a standard installation.
Is it 12 volt negative ground?
Yes. Like the Pertronix distributor line, part D1020 is built for 12 volt negative ground systems.
