Description

The Allstar Performance base plate inserts are designed for use with a 1-inch thick, four-hole aluminum spacer. These inserts restrict air/fuel entry and reduce power slightly to prevent wheel spin, aiding in quicker lap times. The inserts range in size from 0.950" to 1.400" for custom tailoring. This set includes four inserts and fits all Holley 4bbl. 4150/4160 series carburetors.
