FAQ
What is the difference between the 1181LS and 1181?
The 1181LS uses a lobe-sensor trigger that reads the distributor cam and needs no magnet sleeve, while the 1181 uses a magnetic trigger with a sleeve. Both convert Delco 8-cylinder distributors to electronic ignition.
Which vehicles does the 1181LS fit?
It covers many 1957-1974 GM V8 models from Chevrolet, GMC, Jeep, Oldsmobile and Pontiac that used the original Delco 8-cylinder distributor. Confirm your OE distributor before ordering.
What coil works with the 1181LS?
A 1.5 ohm coil on a 12 volt negative ground system is recommended.
Does the 1181LS require a magnet sleeve?
No. As a lobe-sensor kit it triggers off the distributor cam and does not use a magnet sleeve.
