I have for sale a set of 8, new Autolite AR-3924 race spark plugs that were to be used in a 360 LA with Edelbrock Performer RPM heads P/N 60775. These plugs were installed on an engine that is still on the engine stand and has never been fired yet.

It was determined that with just over 13:1 compression, the heat range of these plugs was too hot so an Autolite race plug with a colder heat range commensurate with the compression ratio of this engine was used. The heat range of these plugs is more for a CR of around 9-1. The only thing with these plugs is that there is a little anti-seize still on the threads from the aluminum heads. I would like to get $41.00 for the set of 8 plugs shipped to any of the 50 states.
