This E-Curve distributor drops right into a Ford 289/302 and uses a digital control module to manage the timing curve in place of centrifugal advance springs and weights. Two rotary dials let the installer select from nearly 100 different advance curves, including vacuum advance, and set an rpm limit to protect the engine from over-rev damage caused by a missed shift or driveline failure.
