ATI GEAR DRIVE SYS 429-46

LUNATI/HOLLEY 93130 Features:

The Lunati Gear Drives have a distinctive design that greatly reduces timing movement through the RPM range and are meticulously machined from billet steel for timing accuracy. The four-degree advance/retard can be achieved through either cam gear dowel pin inserts or three keyway crank gears. A heat treatment is applied for durability, and the kit includes dowel pin advance/retard inserts, a rollerized cam button for use with a roller cam and a lock plate with the bolts. Lunati Gear Drives are the right kit choice for street performance applications looking for a blower sound.
