Review DELCO REMY Nos Gm Cyl Inch Distributor Vacuum Advance fits 350

The Delco Remy 1973612 NOS GM 350 Distributor Vacuum Advance is a crucial component in the ignition system of a 1972-1986 General Motors 350 cubic inch V8 engine.

It is designed to provide improved vacuum advance performance, ensuring optimal engine performance and fuel efficiency.

The Delco Remy 12V distributor features a robust design with a durable cast aluminum housing.

It is important to note that this part is intended for use in vehicles with a mechanical vacuum advance system. If your engine has an electronic distributor or a distributorless ignition system, this part will not be compatible.

Installing this distributor vacuum advance unit is relatively straightforward, but it is recommended that the installation be performed by a qualified automotive technician to ensure proper fitment and functionality. The distributor vacuum advance unit should be installed with the engine at normal operating temperature and the distributor cap removed. The new unit is then installed in place of the old one, and the distributor cap is reinstalled.
